favorite : TOUHOU!!! touhou fans are so sweet I love interacting with them so much least fav : visual novels #tbh I'm tired of lolicons and gooners

I had another response for this talking about why I dislike a certain part of the fandoms mentioned, but I think it's too long and negative for a question as simple as this (I don't think I was very coherent either)
Favourite is Omniscient Reader's Viewpoint (The side that isn't the TikTok side, at least)
Least favourite is Jujutsu Kaisen (I've associated with the fandom, unlike with Danganronpa and MHA, which is why neither of them are the least favourite for me)
I saw someone mention Alien Stage and honestly, I can agree with the point mentioned, the TikTok side strikes again, unfortunately (I know certain fans are like the TikTok side despite never being on TikTok, and vice versa, it's just more likely to be the TikTok fans, or so I've observed)

my favorite one ive been in is ROBLOX!!! ALL OF MY FRIENDS ARE FROM ROBLOX!!! Least favorite is gacha life. i dont need to explain why

favorite: probably monster prom... i havent really noticed anything weird about that fandom but maybe i'm just not looking in the right places. least favorite: danganronpa. i assume i don't need to explain that one

favorite: Star Trek. It's a very kind fandom, probably because it's a very old fandom and they've seen everything before, and the average Trekkie understands their favorite media on a deeper level than pretty much any other fandom I know.

least favorite: Evangelion. I don't care which underage girl you think is prettier, I came here to talk about existentialism!
