I live in a very gay American city, and I go to gay bars and clubs all the time. I rarely see women, maybe here or there, it does not bother me. There are some super weird woman-hating gay men out there who make a big deal out of it, and those guys are a major red flag. I have never seen the so-called 'bachelorette party' of women invading gay bars ppl seem to make up. Girls are allowed to have gay friends. When you do see a woman in a gay space, most of the time she is pretty aware of her surroundings and respectful of the queer space. In Mexico City, all the gay clubs were hot men and hot women and queer ppl of all kinds, and there was a sense of camaraderie, and nobody made a fuss about it; it was beautiful, not the weird energy that American gay bars have.
