I am gay too, so  i can say this. I used to live in Toronto's gay village in a large apartment building. There were "party girls" down the hall, who loved to entertain..  I went to a couple of their soirees, but then declined because  they tended to get boozy, and I really had nothing in common with them .  Eventually  they initiated the "We don't see you. We don't hear you", cold shoulder game,  in the halls and elevator.  A civil smile and nod "hello" or "goodbye' just wasn't enough. They confused indifference for hostility. Like may in the LGBT community, their need for approval from others makes them very judgemental of others.
