I do not think that is the case.
No one in my family is gay, but just the way my parents and grandparents handle situations. I know that my family would shun something like that.
On second thought, I think you are right. I had an Uncle who was gay, and I still loved him (he’s passed on now). When I think of him, I can never recall it being an issue. He never demanded this or that, never did anything to embarrass anyone. So, I guess I was just speaking for myself.
