Since I left home I don't really have a religious community anymore so I can only say what I personally believe and how other communities I have been in have acted.
Myself, While I accept that some people are naturally gay and I know longer consider being so a sin, I am a little uncomfortable around them. That may seem insensitive, but you have to understand that I am just now getting over years of church and peer induced homophobia. Really if it wasn't for support from my parents and my bible scholar I would still feel outright hate towards the gay community.
As for other communities, I would say that the most recent church I have been to (I won't name any names) needs much improvement. I was recently talking to a friend who stated that BGLT's could not be serious christian's, that they were going to hell for it, and that the church they belonged to must have been extremely corrupt.
Though I am not gay myself, it doesn't take much to assume that this attitude is downright abhorrent and even a little frightening for BGLT's looking for a strong religious community. This particular statement affected me even more so since I had shared the same beliefs not long ago.
Well, with any luck this little rant answered at least some of the questions you were putting forward.
