The problem doesn't stem from "the guy who plays IG and happens to be gay" and whatnot, because you remember him as who he is and the fact he's gay in an optional information that doesn't affect how you interact or play with him.
The problem comes the type of gay, trans, girl or whatever that will DEMAND that you see them as unique (and sometimes superior) because THEY are special and they'll remind it to everyone like their lives depended on it, as in, if they don't express or show it everywhere and explicitely, they will suffer immediate "zero sum".
Remember that one internet "law" of "there's no woman on the internet"? because that was made so everyone is considered a user because that way, no woman would be able to use their "tits&vagina" status to abuse the weak minded and the desperate, and at the same time, women wouldn't be stalked and discriminated against since they would be worth as much as any other user.
Now, tit's a joke (a very offensive one, apparently) and you see people that identify more about their sexuality, their "gender" or whatever cause they fight for than their actual personnality.
It's also that kind of "That Guy" on steroid that will demand more representation for "minorities" in a game they don't even play.
I mean, they are the kind that will ask for more female representation, but once you put a female character, they'll then say the boob plate objectifies her so you have to remove the boobplate...
And then she looks like an androgynous dude and you get what happens with the new Commissar girl model.
And while this happened... well the oes that complained won't buy any model, and since they removed the boob plate, it doesn't appeal to the hardcore fans that may like the model of a female to be feminine. So, it tanks, and shit gets bads, and they'll find something else to complain about.
tl:dr, people don't care about if you're "weird", because they are too, they're just sick of the obnoxious ones that ruin their hobby.
