It’s the sexist comments, boomer humor, male-centric views, the mansplaining, the chauvinism, the micro-aggressions, lack of empathy from a lack of perspective, the oversimplification without nuance, etc. All that generally makes women uncomfortable and sometimes it’s a bit much. Sometimes you want to forget those exist and focus on what matters to you with like-minded people.

It’s the same for us gay folks. I know I can’t just bring up whatever gay topic in a straight group where not everyone can relate, offer their first hand experience, or might find it weird because it’s not part of their lives.

Trying to concentrate similar people to discuss common topics is, at the very worts, a constructive division.
