Fandom in general is pretty autistic and degenerate, in my opinion. Doesn't matter what it's a fandom for, or even if it's Current Year or in the past. "Fan" comes from "fanatic" after all. Especially since people started making their hobbies into their personality which, while more prevalent now, has always been a thing...it's always been the extreme weirdos. They just used to be less weird, and more genuinely passionate. But I can tell you, even two decades ago, those in the "anime fandom" as opposed to just "anime fans/enthusiasts" were creepy weirdos.

TL;DR: "Fandoms" are gay anyway.

But I get what you mean, too. Even not getting into the technicals about "fandom" versus mere "group of enjoyers," it's getting harder and harder to find a group of people who enjoy anything, without it having a bunch of gay trans shit inserted into it. Anime, video games, tabletop/D&D, movies/TV, politics, books...everything is overrun by the gay scourge right now.
