I've been to hundreds, maybe thousands, of social gatherings--church, neighborhood, clubs, academe, etc.--almost everyone is white, mid-west and Christian, but a few are black and Asian, particularly when I was younger. Always by choice men and women separate themselves and discuss what they care about--sports, children, career, fashion, food. If the event is art or music, there might be some mixing, but by the end of the event, even those are divided by gender. Now that I’m retired, age is the big divider. Now a Muslim woman objects.
