I’m female, so I didn’t vote in the poll. And I hesitated to post to the thread, too. I tend to try to hide my fandom vices from anyone who isn’t a fellow fan IRL, and some fandoms I hesitate to mention at all. Sadly, this is one of them, but not because of personal distaste or guilt, so much as a widely spread poor view of it, which I feel has been somewhat demonstrated in the thread already.
I’ve been to two Brony conventions (convention-attending is one of my favorite hobbies) with very different moods. One of them was a failed convention, and the second-worst convention I’ve ever been to. (Las Pegasus, if any of the self-professed bronies in the thread are curious.) People weren’t unpleasant, there were lots of guests, but there weren’t enough attendees and both the dealer room and artist’s alleys were kind of depressingly empty. The other con, on the other hand, was one of my favorite con experiences in recent memory. People were friendly and helpful to each other, I had a good time chatting with other fans in line, etc.
I’m sure one and I think both the cons had a complete ban on erotic works in the dealer and artist rooms. Both cons also had a range of attendees, male and female, some older than myself and some much younger, including children, and I didn’t see any sign of misbehavior. I saw one young woman in a Fluttershy costume asked by a normal hotel guest to pose with his daughters, who were clearly thrilled to be unexpectedly surrounded by ‘ponies.’
I won’t deny that the porn-creating section of the fandom can easily cause spontaneous, self-defensive blindness if viewed unexpectedly. And I will say that I do think some of the porn-lovers are genuinely fans, who like fans in many fandoms, want to dirty up their hobby for their own fun. I don’t really mind it as long as it’s clearly adults, drawing adult characters, for other adults. That said, I haven’t really had trouble avoiding porn, although I have made a slight effort to avoid it (I do not look at the MLP tag on tumblr, for example.)
Really, I think a lot of the bad rep is a mixture of people being annoyed by how big the fandom is, and the fact that a fandom so big means there’s a greater number of people who’ll be particularly ill-socialized. I’ve experienced that sort of behavior at sci-fi, comic and anime conventions, so I don’t think it’s unique to MLP. What may be unique to MLP is the combination of a poor impression going in from non-fans dealing with fans, and the increased chance that someone will have a bad encounter with a ‘brony’ because there are so many of them spanning a wide range of behavior.
