If the Gaystapo want their own version of Christianity, they can start their own church.
Why not follow in the footsteps of Protestants, Episcopalians, Presbyterians, Methodists, Baptists, Catholics, Mormons and all other branches of the faith?
Everyone has the right to believe wha they want, but you can't hijack an established religion. You'd be guilty of forcing your beliefs on them. If it's wrong for them to do to you, then you doing it, even though you think your beliefs are better, is still wrong.
I applaud the desire to incorporate religion into the Gay community, but trying to incorporate "gayness" into Christianity isn't the way to go.
