I've found that a lot of them base their entire identity around gayness. instead of having a rounded set of interests, they spend all their time at gay meeting places like bars, gay activist groups, gay university clubs, gay bathhouses, synagogues etc.. there are gay variants for literally any group imaginable, and like anything else, if you spend all your time with people who think exactly like you, it turns into an echo chamber and you lose touch with reality and become unable to accept opposing viewpoints.
I never understood how this came to be acceptable. Think about it, gay book club, gay aerobics, gay knitting - why the fuck do these things need a sexual preference prefix? I-Like-To-Fuck-Dudes-In-The-Ass-Knitting. Just... Why? I sat at a friends birthday thing for his son and his brother sat at the kids table and EVERYTHING he said had to do with gayness. No one even asked or questioned his sexuality and it was a kids birthday party so it shouldn't have been a subject of conversation to begin with, which I found EXTREMELY odd, no one called him out on talking about SEX at a 8 year old's birthday. Just because hes gay everyone is afraid to tell him to speak on appropriate topics or shut the fuck up? Like... Just because its GAY sex, it's ok to discuss with kids? What?
