AMEN Keith! One of the biggest obstacles in attempting to win my LGBT friends and some straight relatives to Christ has been the NASTY and loudly judgemental attitude many churches have had about perceived "Alternate" lifestyles (like going hot-air ballooning rather than attending church on Sunday--the horror!) toward them, to the point that when Haruo and I were doing music programs we felt might be entertaining (these were secular music programs and a silent movie) and invited these people, they had excuses why they could never come, and I was told by one uncle point blank, that he never sets foot in a church building.
If you can't bring yourself to be "Affirming", at least be WELCOMING!!!
Don't despair if your job and your rewards are few, remember that the mighty oak was once a nut like you!
