Word of advice, just so you can enjoy the fandoms you appreciate; do not engross yourself with stans.
Find someone you can talk about the matter with, someone that won't be rude. And ignore the awful comments on your stories, feed, etc. that aren't constructive. It's as easy as reading and then ignoring, or just straight up ignoring. You shouldn't have to dislike something just because of rabid fans. That's dumb because anonymity gives everyone the chance to do what they want, and people get mean on the internet. It's just the nasty flood of internet culture we live in.
Enjoy what you like. If you fall off due to your own self growth, that's good! People change, but don't let others change you, Babs ♥️
Find your niche and stick with it until you decide personally that it's okay to leave ♥️♥️
Pick what you like and don't let anyone make you feel bad for your passion!
(AND I've seen this with so many fandoms; BNHA, Septiplier shippers, One Direction kids, FNAF, Minecraft, Pokémon, several animes, and y'know what? Every fanbase has the potential to be toxic, it's just how well you can avoid it! Safe travels, loves)
