Alcoholism is degenerate behavior. Gay sex is also degenerate behavior. Both have negative social and personal consequences. The culture that gave you all of the good things you enjoy in life called these behaviors "sinful" and they were discouraged up until 20-30 years ago. And my point is that, if you know your friend is actively harming himself and you do nothing to help him, you aren't much of a friend.

I don't believe my two friends that have sex with one another are hurting themselves or slowly killing themselves so I don't reach out and ask them to stop. If they were alcoholics, I would talk to them about it and try to help them.
Okay, so you would talk to your friend if you believed their behavior was damaging to themselves. We are in agreement on that. I happen to believe homosexuality is damaging to men and you don't. As I said earlier, at a minimum homosexuality is genetic suicide. So you are happy that your friends are effectively voluntary eunuchs. I think that is quite sad.
That's okay man. They provide to the world in other ways. 🫂
I wouldn't want to be single and childless on my death bed. That is sad.
Me either, man. My kids are the best parts of my life. People that don't want kids confuse me a bit, because they would be missing out on so much love and joy. I would accept their decision even though I don't fully understand it.
