For the past few years, one of my good friends has been going downhill. It started out with him saying subtle things that I didn't agree with, being racist and sexist etc. I guess because it was a slow build up, a lot of my friends and I chose to ignore it. Now I really struggle to be around him because he can't see why I don't sure his hatred for muslims, gay people etc. As as result, I don't see him that much anymore and I know most of his friends are the same.

He has become very isolated and distant and I'm really worried that he might do something stupid. I feel horrible about it because as much as I want to see him happy and make sure that he doesn't harm himself, I feel like I can't be bothered to see him. Does that make me a bad person? What should I be doing about it?
