So, will they or their religious views survive? Will being proven wrong on this issue, and issue that they have made so much of, weaken their moral authority on other moral issues? What do you think?
The adherents of the faiths you mentioned are quite good at ignoring scientific evidence, as well as contradictory and immoral passages in their holy books. Most people in general seem to lack decent critical thinking skills...adding a new variable to their limited world view will do little to change their minds. Moreover, judging by where we're at with the
fact of evolution and it's extreme LACK of acceptance...we would probably end up with a whole new group of inborn-homosexuality deniers. Maybe they'll name their cause "Intelligent Sexuality" (IS for short) or something just as ridiculous.
Even if homosexuality is completely proven to be determined at birth (which is likely) the religious leaders will still be held in high esteem by their flocks, and accepted as moral authorities by those who don't know any better or need someone to tell them how to live their own lives. The wiser of these leaders will adapt their teachings to accomodate the acceptance of homosexuality, otherwise their churches will likely fade to the fringes of belief currently occupied by the more extreme, backwards thinking hate groups like the neo-nazis, or the KKK.
Keep in mind, the success of a meme complex does not depend on it's truth (or lack thereof) but rather how well it serves to bind people together and function as a social glue.
