There's activism and there's performing the very same evil you claim to be against. What happened with a Steven Universe fanartist named Zamii070 falls into the latter.

I may not know the full story, but from the evidence I gathered, Zamii070 was being constantly trolled, bullied, and terrorized by Social Justice Warriors on Tumblr for several reasons, from posting fanart of characters drawn by a person she didn't know was a sex offender, posting ignorant language about people who were trans or fat, and drawing a supposedly chubby Steven Universe character a little skinny. Whatever the case is, I don't know. But for the past year, SJWs, especially ones in the SU fandom, stalked and bullied her. In fact, several hate-blogs (called "receipt" blogs or callout journals) chronicled her posts. Consider the fact that she was online to get away from the abuse she suffered in real life.

Lately, because of a fanart that SU SJWs got into a tizzy and shredded her with hate, Zamii couldn't handle it anymore and attempted to take her life. Three days later, she posted this video telling everyone she survived and was getting help. You can find a lot of the drama covering why she attempted suicide here.

For the past few months, I've seen some really sick stuff.

1. Recently, trolls bullied a two-year-old boy because his father build for him a kitchen playset. The bullying was sexist, transphobic, and homophobic (trolls called the boy a "faggot"). Garbage like this is why "don't feed the troll" doesn't work: There should be no tolerance for trolling, period.
2. For the past month, there's been a rise of a very demonizing anti-Lauren Faust conspiracy theory here. The claim is that Faust joined Mane6, felt the fandom didn't cherish her inspiration and creative wealth while she worked on the show, and responded to a ten-year-old girl whose letter was destroyed by a Hasbro office as a way to be a greedy, profit-seeking, passive-aggressive, whiny bitch to Hasbro and Friendship Is Magic. How anyone can believe such bullshit is beyond common sense. There's a way to be critical of Faust without looking like a dick! But this isn't criticism of her. This is character assassination. A perverted vendetta. Nobody deserves it!
3. During the summer, a transwoman in Michigan was slandered by a woman who claimed a man was in the Planet Fitness locker room. Because PF refused to do anything about it because the woman identified as such, the ciswoman spewed BS around claiming they allowed men in the locker room. What do you guess? The ciswoman was banned from the Planet Fitness. A website called GenderTrender posted transmisogynist crap all over it, from the post itself to the comments. A TERF named Roslyn Holcomb (an African-American romance author and vocal activist in the black community) wrote in a comment that if she saw the transwoman in the locker room, she'd immediately kill her. Transwomen aren't going into the women's locker room to get into your pants. They go into the locker room because they don't identify with the opposite gender. Locker room privacy for trans* people is an imperative civil rights issue, and Planet Fitness understands this.
4. Public shaming of kids, notably a depressed girl who committed suicide soon after her father shamed her by cutting off her hair and making the school announce that she wouldn't run for a very important student body. Only a sicko would think of humiliating a child as punishment, and only a sicko would think of applauding such garbage.
   

As far as Tumblr "justice" is concerned, this crosses the line into one of the sickest displays of evil that I've ever seen. This is far beyond being a "gatekeeper" to prevent bronies from being a fan of the show (including one SU SJW who "rallied" to commit cyberterrorism against them, only to run after getting chewed out) or chasing a writer of the show from Tumblr. This is 2000% worse.

SU SJWs, I don't give a fuck what your grudges are towards this girl. I don't care if she said some stupid things in the past. This girl is as much a human as you and I. She was clinically depressed and went online as a way to escape from the abuse her family gave her in real life. The Internet provided a gate to share her talents and be happy.

There's ZERO excuse to bully anyone, period! Your grudges don't entitle your privileged asses to stalking her, threatening her, chronologically recording every single damn thing she wrote and drew in her blog, and telling her to kill herself! Let me repeat it again, you have no right whatsoever to tell anyone to kill themselves. To tell them this is the same as sending a death threat. To send a death threat is terrible enough; to send one who was mentally ill is beyond demented!

And over what? Fanart of a Steven Universe character?! I normally don't like saying this, but Steven Universe is just a show! There's a major difference between taking a show seriously and taking one obsessively to the point of being personal. Guess where this falls. SU SJWs, you don't exclusively own the show. It belongs to everyone! Yes, including incoming fans.

Now that she tried to take her life, you had the gall to gloat over it, save face by wiping out your accounts, and put the blame on her?

Y'know, this reminds me of what happened with Chris-chan. Trolls/bullies/terrorists from 4chan stalked him, posted every single thing about him online, and doxxed him. He actually spent some time offline because it was too much for him to deal with. To make it worse, there are people who literally say he deserved to be trolled. To blame Chris-chan for any of the trolling regardless of the crap he says is to blame the victim, and you have to be a complete sicko to think of blaming him.

HOW DARE YOU ATTEMPT TO BLAME ZAMII FOR SOMETHING THAT WAS YOUR OWN DOING!!!!!

Thank you, Social Justice Warriors, you've achieved a low equivalent to the 4chan trolls on Chris-chan.

Now look what happened:

1. The Steven Universe fandom's reputation is now damaged, and possibly beyond repair. The show is great, but no one will want to venture into a fandom with a solid portion being so verbally violent.
2. Tumblr's already terrible reputation is now worse. One of the earlier great things about the website is the ability to spread messages of good, bad, and ugly, and being proactive about it. But over the past few years, Tumblr's been infested with disgusting displays of Social Justice Warriorism. You claim to fight for social justice, yet you're no less sexist, racist, and homophobic than the people you claim to be against.
    
   
   And seriously, who in the hell would want to be a part of a website that's so toxic and mob-like, they fear that their lives will be ruined if they write something stupid?
3. You claim to be gatekeepers to prevent bronies from "infesting" the fandom with R34. Guess what? Too fucking bad!! Bronies have been SU fans and vice-versa long before you started pulling such shit! Thousands of SU fans have already uploaded porn, and there's a good chance several of them aren't even bronies. You won't stop bronies from becoming a part of the SU fandom. You won't prevent Steven Universe fans from drawing or writing R34.
4. You created a very disgusting stereotype of how every SU fan is an overly sensitive bigot. Do you know who this will hurt the most? Upcoming fans of the show. Fans who have no idea this drama even existed. Fans who will be bashed the second they proudly admit they love the show. The passersby will be big targets to a lot of bullying because the Tumblr SJWs in the SU fandom helped drag the fun out of sharing to the fandom in the first place. Now imagine if the upcoming fan being bullied is a kid who doesn't go deep into the fandom.
   

Seriously, do you have any idea what you just did? You and your evil made someone consider taking her own life. Now, imagine if she succeeded. You'd be on the news because you thugs murdered her.

I can see the comments now:

1. "Don't feed the troll."
2. "If she ignored the bullies, none of this would've happened."
3. "Grow a thicker skin."
4. "She's weak for attempting suicide."
   

Don't! Even! DARE!

1. What happened to Zamii is far beyond a pest annoying her. Zamii was being bullied for a year by hundreds of people, many from the very fandom of the show she loved, before she tried taking her own life. It's one thing for an experienced adult in a profession trying to ignore it. It's another for a fan, one much younger than many of us here.
2. Imagine having to go online every day and try to ignore abuse by hundreds of people who mock you every day of the week, harass you, and stalk you beyond the Internet. All the while trying to not think about the abuse you endured in real life and battling mental illnesses that affect you every day. Do you have any idea how tough it is to ignore it? How tough it is to think that one comment with unfortunate implications could cause a mob to harass and maybe doxx you?
3. Anytime you say "grow a thicker skin," you're not being mature. You're saying, "It's your fault you're being abused." Much like the other two above, this is classic victim-blaming. You don't look cool, tough, and adult when you say it. You look pathetic. Instead, why not be an actual adult show actual empathy?!
    
   
   Often, when we think of abuse, including domestic violence, we think of physical violence. Verbal violence exists, too. Words are weapons. Words can hurt. Words kill. They're not empty. Think about it.
4. No. Just…no. Do you know why many people attempt suicide? Because they feel trapped. Many targets try to take their own lives because they see it as the only way out of their bubble of horror. Depression is an illness; we don't talk about it without exploiting it. It's a very serious issue, and we take it for granted.
    
   
   Do you know how many comments it takes for someone to attempt suicide?
    
   One.
    
   Zamii had to sift and ignore hundreds of shitposts and hate-blogs dedicated to her, and she attempted suicide because she felt it was the only way out. She has to live through their sociopathy online every day for at least a year, and there are still plenty of people verbally abusing her after she posted her suicide note and vlog from the hospital. Everyone has a breaking point, and we don't know where or when it is.
   

I've seen so much fandom drama over the past ten years. Alongside the terrible infestation of sockpuppets flaming young authors on Fanfiction.net because they wrote poor-quality fanfiction and the 4chan trolls stalking Chris-chan for eight years, this easily ranks as one of the worst. This isn't cute or funny. This is a hivemind that went completely out of control, and now Tumblr and the Steven Universe fandom as a whole may be paying a steep price.

There are no words to accurately describe how heinous this whole thing was. Nobody deserves abuse, much less a twenty-year-old.
