You could replace that with just about any other fandom based around a TV/movie franchise and I guarantee it'll probably be the exact same. I am thankful every day that I don't join specific communities based around individual show/movie franchises because of how toxic they can get.

Point out to certain fandoms either some major flaw or the fact you don't like the show and some groups will act like you just committed a 9/11 style terrorist attack on their show. Same thing even goes for creators of the show sometimes. We really need to end fandom culture.
