It’s a culture thing. A majority queer group hanging out vs a majority non-queer group is a totally different vibe, to the point that like the original post, it feels weird to me to hang out with a bunch of straight people, as the slang, mannerisms, and social code are just totally different. As the other commenter said, neurodivergent people are also more likely to question other aspects of their identity, so there is a lot of overlap between the two groups as well.
