Don't get me wrong, when I say "bronies who perpetuate rape culture", I actually mean bronies I have seen/met who have the opinion of rape victims ask for it and rapists are not to blame in any case. As much as I personally hate rape jokes, I've come to terms with them. They offend me to no end, but I don't think any longer that they advocate rape. I realize that and I get it. I just don't get why people think they're funny in the first place. I would go on, but thinking about it? I'm probably going to severely offend someone soon so that's all I will say XD
Anywho! In my own experience, I have not had the pleasure of seeing the good in this fandom overcome the bad. I have only ever witnessed good brony things on this site and Deviantart (and even then, it's just good art XD). However, compared to other fandoms, we can't say we are or are not better/worse than fandoms in general. Unless we gather an accurate consensus of every single fandom, it will be impossible XD But that doesn't mean we can't compare to some of the most well-known. Furries, for example, are a popular one that bronies are compared to when it's actually a really bad comparison. Furries are considered less of a fandom now and more of a sub-culture. Just as well, furries have been around a lot longer than bronies so it's like trying to compare 2013 as a year to 0-2012 as a lifetime XD
I do agree bronies have done good things! it's great! But it still doesn't change my mind and it's not going to make me think that I should shoulder any of the burden for the better of the fandom. D: At the end of the day, it's just a fandom and I don't need it anymore than it needs me.
