I have gotten hundreds of comments on my videos. Two of them were hateful. And they were downvoted into oblivion.
So I don't really get where this "haters" thing is coming from. I haven't even experienced it.
And as for fads, sometimes people don't dig on the show but the love the things that come out of the fandom. For example, Touhou makes me nauseous, but I love Bad Apple. And I don't care for the core Star Wars films, but I love the extended universe stuff.
It's also worth noting the fragmentation in the fandom. Many bronies prefer pretending that the furry segment of the community doesn't exist, despite the fact that they make a huge portion of the quality fanart. Personally I steer clear of the odd phenomenon that is shipping, and Rule 34, and consequently I pretty much stay away from fanfiction. There's also the grimdark stuff... it's a little perplexing to me why it even exists, considering this show's major draw is how unflinchingly bright and cheerful it is. That's just me tho. Judge not eh.
"Dear Princess Celestia,
Today I learned that it's okay to be passionate about the things you like, but that it's important to not to be a derp spaz who thinks lack of shared enthusiasm is like persecution or something. Derr, how does I subtlety?
Your faithful student,
The Internet"
