Well, as far as I know, there are none. That's not to say there isn't, only that I don't know about any....
However, my son-in-law has a sister that came out as lesbian a few years ago and he was fit to be tied. He has ranted at her and the rest of his sibs etc. about it. He's a very outspoken fellow....
Anyway, my hubs and I have had to listen to him ranting about it and at one point, even tho' I do not condone her lifestyle, told him that regardless of her sexuality, she is still his sister and he should be respectful of her just for that reason alone.
I believe, that with the passing of time, their relationship has gotten better and he isn't so apt to pound that topic into the ground as he has so aptly done in the past.... For which I am thankful.....
