This shitty thing. It's fairly infamous among non-normalfags both for being staged and full of bullshit, as well as for the finance magicks they pulled. De Lancie (one of the actors) even tried guilt tripping the fans over pirating the thing and tried to persuade them to give him more shekels for it (despite the whole thing being crowdfunded by fans in the first palce). He got very triggered after being told to eat shit in response. It's fortunate the VAs don't get any input into the actual script, else it really would be full of faggotry.
They really are not. Take it from someone who actually went to some cons and doesn't get all his info on the topic from cringe threads and memes.
A large percentage of bronies (something between a fouth and a third) have legit autism, usually mild cases, and there is indeed little point in talking to them because, hey, they're retarded. They don't tend to be actually cancerous, however. They're mostly lurkers who, if they actually do have the courage to visit a meetup or a con, just go there, sit, watch without saying a word, and ho home.
Then you got normalfags that came in after MLP became really popular in 2014/2015, and they do the regular shit normalfags do. Suck Hasbro's dick, spend ridiculous amount of money on merchandise – standard normalfag behavior.
Then you get the actual, non-autistic fans. Those tend to be pretty alright, ranging the nerds you'd normally find on sci-fi cons to imageboard types. They tend to be pleasant to hang out with, and usually form small groups to segregate themselves from normalfaggotry. They often clop, but they don't show it, don't talk about it, don't propagate it, and usually limit themselves to admitting to it and moving on. Not that they're in any way so polite and refined, but they're not obsessed about porn, have at least a basic knowledge of etiquette, and there are always more interesting things to talk about than endlessly discussing what they jack off to.
Then you get the last, most cancerous cathegory, which are furries. They're insufferable, and the reason why bronies are known to hate furries so fucking much, despite the apparent outward similarity. They're the cunts who dress in fursuits, they're the faggots who brag loudly about how they masturbated to a pony being ravaged by a wolf, they're the ones who look like they're rapists, and make rapist-like remarks due to having no fucking idea how to function in society, and they're the ones so obsessed with pornography that it's literally the only thing they ever want to talk about. I've been to dozens of meetups and several cons, and every single time I see some degenerate cretin talking about horse pussy, it's a fucking furry. Every fucking time. When I go see the cosplayers on a con, most of them go for something like pic-related, but guess who brought a fursuit? That's right, a furry. When someone on a meetup says he wants to show us something, and pulls out an r34 poster (in a way so that the whole café can see it), guess who that person is? A furry again! As I've already said, I toured many meetups and cons. During these visits, I've seen extreme amounts people who were awkward as fuck, many who were downright stupid, a good amount of bro-tier guys who downed a few beers and actually had non-retarded opinion on politics (which we discussed, among other things), but very, very few outright faggots and degenerates who weren't furries.
