This is interesting I have a friend who became a hardcore christian extremist a few years ago and he had a gay best friend. The problem was not the fact he was gay but that whenever they hung out all his gay friend wanted to do was drink, do drugs, party and have multiple partners. They aren't friends anymore because of the way his gay friend chooses to live a care free life.
Live every day as if already dead, that way you're not disappointed when you are.
