There's also a theory that goes 'if you're already coming out as gay, embracing furriness seems meaningless in comparison'.
Like, there might be straight people who might like furry stuff but refuse to engage with anything outside strict 'normal' but if you're already outside 'normal' then it's a lower barrier to entry.
Also early furry history is pre-internet and was spread through conventions and zines and other methods that were very popular in the gay community.
If you were gay it was hard to find other gay people when outing yoruself to a random dude was risking verbal abuse or worse, so underground communities could meet up at conventions and feel safe, and hey while they were there they'd also actually look into this furry stuff. Why not, they were already at the hotel to find other gay people, let's go see what this furry thing is. Right?
So there are a few factors that go into it, and it's all very intersting actually. Cool sociology stuff, but the bottom line is more than 50% of furries are not-exclusively-straight. At the very least bi or curious or w/e.
Anyway, I doubt any given community, gay, straight, fetish, normie, whatever, is any more likely to go and shit up some thread by asking the game devs to change their focus to suit themselves. But the fact there are way more straight people and, outside of furries, fewer gay games, means you're going to see a larger number of folk shitting up a smaller number of threads. It's still gonna be like 1% of people who think this is acceptable/reasonable behavior, but the straights are going to be the larger absolute size group that are doing it.
It's all crazy annoying though. People should just go find games they like instead of trying to change games they don't like.
