Religion pre-dating 1000 A.D. and homosexuality will never be compatible with each other for the sole reason that homosexuality in a limited perspective flies in the face of procreation.
Babies back then died left and right and the amount of newborns that made it to adulthood were scarce. So religion dictates to make as many babies as possible or the population will die out. And it was particularly valid at some points in history.
The only "real" religion that I can think of that is "compatible" with homosexuality is Buddhism.
Anyhoo, let people believe what they want to beleive in. Public opinion of homosexuality is rapidly swaying in favor of view homosexuality as a normal sexual orientation. I predict, barring any crisises, that homosexuality will largely be approved by the world by 2100.
