What I don't get is the amount of hate bronies get AS A GROUP for the sins of a few. To the right wing they're a symptom of the waning masculinity of society. To the social justice types they're misogynistic brutes who took one of the best modern feminist cartoons and turned it into their sex object, all while adopting a persecution complex that belittles the struggles of actual oppressed groups.
Do you know what opinion I don't see often? That they are a large and diverse periphery demographic of a well-made cartoon, among them both bad people and good people.
And it's entirely possible to mostly avoid the bad ones. Mainstream communities in the fandom like Equestria Daily generally do their best to keep things family-friendly. Local meetup groups can set rules to keep their meetups friendly, whether it's by limiting themselves to PG discourse or by limiting their exposure to the younger target audience. Cons are, from my experience, mostly positive experiences where, while you might run into more unsavory folks (as you might at any large gathering or convention), largely keep their tone welcoming and supportive and maintain a positive atmosphere. And most communities do plenty of good, whether it's by inspiring creativity among its members, supporting charities, or just going to the people who bring them the show and letting them know how much they're appreciated.
Seriously, stereotyping is bad. Every time you call bronies as a group "neckbeards" or "perverts" or what have you, you're facilitating a persistent and broad stereotype that affects both the good fans and the bad ones. As an exercise, think about a group or subculture that you yourself are a part of, be it animé fans, gamers, sports fans, or even Lego fans. Now isolate the worst aspects you've seen in a member or members of that group (be it misogyny, cultural appropriation, perversion, rudeness, whatever), and see what it's like to label yourself as that. It's not nice, is it?
One last note to address a common complaint I see: that the good people in the fandom are themselves guilty for associating with the bad ones. This is a false argument. Again, let's relate things to another fandom, that being the Lego fandom. I've seen plenty of misogyny and other bigotry within this fandom through my time on Eurobricks, Brickset, and even BZPower. But I'm not about to quit using those sites (or calling myself an AFOL) because of that. If I did, not only would I be missing out on a lot of the most relevant news and discussion to my interest in Lego, but by divorcing myself from the group, the group would itself become worse due to losing one more voice of reason who's willing to argue with its worst members. Rare is the group or subculture that maintains acceptable attitudes in all its members, but if you isolate yourself from any group that has one or more less-than-perfect members you're going to find yourself awfully lonely. By remaining there to combat regressive attitudes, you can make your part of the world a brighter place.
