You have every right to be concerned for your friend. Listen, that is dangerous even when your straight. Even going out with friends getting tanked and getting separated. Where I live, there is a vast amount of night and dance clubs straight and gay just a short drive from the suburbs. Woman and men get drugged and raped. I happens a lot.
I had a friend whose mom would let her son and his friends drink at their house as high school upper class-men. Not good, but we were not bar hopping. I went bar hopping A LOT from 18 to my early thirties, then I stopped completely. There were some fun times and some very bad ones. To tell you the truth, I feel lucky to be alive when I look back now. Today for me a wild night out is taking Uber to a Christmas party.
Warn this kid, pray for him… no one was praying for me, and let it go. Prayer is far more powerful than most people think. Seriously. As far as being gay goes, that in of itself is a huge cross. All you can do there is pray that he will pick up his cross and follow Christ.
Gay people I do think offer a different point of view that can have valuable insights into some things, But like all of us single people, they have to pick up their cross. They are called to celibacy just like any other single person. Life, I think, is a process. It isn’t easy, and it was never supposed to be after the garden.
Pray for your friend and all people who struggle with their crosses. You sound like a very nice person.
