Yeah...I love MLP BUT I agree that the fans are annoying as hell. Well, most of them are anyways.
The MLP portion of memebase is painful- they try giving all these inspirational speeches about something that a FAKE MAGICAL UNOCRONPINYWHATAEVErjEFAHK DID. And I'm just like. NO. Stop. NOW.
OR, they'll act all high and mighty about this "love and tolerate" crap. So when someone attacks them they're like "I'm gonna love and tolerate the shit out of you" aand I don't even know if that's supposed to be clever or what, but shut up, because you suck.
I love the show, collect the toys, buy the comic books, buy the clothes, make customs, draw characters, write fanfictions, talk about it constantly, fantasize about kissing Rainbow Dash, write fanfictions, buy the comic books, talk about it constantly, only draw ponies, fantasize about kissing Rainbow Dash, etc.
That might be why they say "no such thing as a sane brony". I see a brony as someone who just likes the show, but unfortunately there's people who go so far as to "clop", make toys, etc... it gives the sane, calm, respectful part of the fandom a bad name.
Whatever. Im' a 20 year old woman dating a 21 year old man and we both like ponies. It's whatevers.
My niece watches that show. She's 6. It's kind of odd to think if we were on the subway, and she sat next to a 35 year old man in a pink T-shirt who was a hardcore brony, they'd have something to talk about o_O. Although I don't think I'd let that happen...
And games, movies and books have all inspired gruesome deeds in the past. Does this mean we should forbid them? of course not, because not allowing these things would infringe upon our personal freedoms. On another note none of these things I mentioned nor your example fotball causes violence. It is true that people are sometimes inspired by media but no media is the instigator for that violence. The people are the instigators and those who play the role of an instigator would probably do so even if they had another hobby.
Every single fandom has their nutjobs. It seems like MLP has a lot because right now MLP is a huge thing and it's everywhere so the chances of running into a crazy fan is increased. Cloppers are sickfucks though.
