Hi there, I also have nothing to do with makeup or following beauty standard or fashion ... however I have friends who do, and sometimes they like to talk about it. So ... I just zone out and let them get on with it, it's not hurting me.
Men dominate 99.9999% of online spaces, and even the most supportive of ally men will sometimes talk over women or assume their opinion is more important, so I think that maintaining this as a space just for women is a good thing.
