Son came out of the closet?

Our 16 year old told me and my wife tonight that he is a gay. I am shocked and we immediatel;y began telling him that his choice will destroy him and this will lead him to AIDS, loneliness and poverty. I have invested so much into his education and upbringing and now he lays this one on me. We told him we'd put him into counseling but he's refusing to go. No one else in our famioly will want anything to do with him due to his perversoon but as much as I hate what he's chosen do I want to kick him out? Our minister has told him if we keep him we won't be allowed back at the church. I'm afraid we'll have to kick him out..... but... Idk. what do you think?
