Excellent point. I would think at the very least any jw who openly admitted to being gay would be ostracized beyond belief by the other jws, regardless of whether he was celibate or not, either that or some loving bros and sis' would try to find him a nice sister to marry, and 'cure' him hehe. I would think most people with strong homosexual tendancies would feel so unwelcome and repressed within the jw org they would leave at some point. Two clear things I noticed which were widely acceptable in the jws, in an unspoken sense: 1. Overdrinking alcohol and 2. Saying cruel and nasty things about gay people, even using clearly unjehovah-ish words to describe them, such as 'poof' or 'fag', etc.
Then they would have studies of certain books which would seem to throw an admiring light on people like Alexander the Great, who was a little light in the sandals by all accounts....(not to mention an alcoholic mass murderer).
