anything related with the country of brazil
you forgot the whole cs fanbase
honestly kpop stans are worse than all of those combined and multiplied by 10. If you were anyone with a remotely decent following and said "lol i dont really like BTS/blackpink/etc" you'll get a bunch of retards getting absolutely berserk.
I dont know how it ever got to this point. I'd like to think it's just preteen girls with no hobbies, but i've seen grown ass women on twitter go apeshit on random twitch streamers for not liking kpop.
sh1ro fans and gambit fans
delusional s1mple fans
delusional s1mple haters
Mouz, Vitality and NaVi fans
specially those who pretend "shounen are good"
at least those who watch loli shit knows it is garbage, but they cant stop, like drugs
persona fanbase, smash fanbase, fnaf fanbase, undertale fanbase
Any stans on Twitter are awful especially the k-pop and Ariana grande stans.
