@blatham,
That and Paul. He had a problem with LGBT people too.
The thing is Leviticus bans all sorts of things, like mixed cloth. So if you're wearing cotton nylon socks you're defying Leviticus in the same way.
The problem is certain "Christian" groups seem to ignore that.
To the OP, there are plenty of gay Christians out there, and plenty of churches are welcoming too. Over here the Rev Richard Cole is a very popular figure, a gay Anglican vicar who used to be a member of the Communards.
Google gay/lgbt Christians in your area. There'll be more than you think.
You don't have to tell anyone. What you do in your own home is nobody else's business. There's no obligation to come out.
