Why do religious people not approve of homosexuality?

[Xdea]

Actually the ancient pre-christian religions embraced homosexuality because they saw it as power in gender, Gods such as Apollo and Diana were worshiped by gays and lesbians because that was one of their God traits, of gays and lesbians. Also many ancient Gods were bisexual, such as Zeus.
Valentines day if I remember right was a day that was mainly focused originally on gays and lesbians as well as celebrating all sex and love on that day by the ancients in Rome and Greece and had parties in honor of Apollo and Diana.
The Druids and native American-Indian's believed that being gay or lesbian meant that you had two spirits and you would then have a good place in becoming a priest or priestess, even an adviser to the ruling person at the time(usually so that if you were gay the king wouldn't be worried about you sleeping with the queen).
In ancient Egypt, homosexuality wasn't really cared about as the people didn't actually pay attension to it, there are pictures of a pharaoh, I forgot his name, how he was a gay pharaoh and it shows him and this other man doing the nose kiss, having their noses touch, it was seen as the most strongest way of showing affection in the ancient Egyptian world for a time, and pharaohs were seen as a God too so it brang religion into it.
With Hinduism, I'm not sure about homosexuality but if your born transgendered you're seen as blessed by the Gods themselves as Shiva and Kali? in human form as one physical being.
Ancient Sumarian's believed that if you were born gay or lesbian, you were advantaged by birth because the Goddess Inanna blessed them to become sorcerers and diviners before they were even born and they would have an advantage of becoming a priest or priestess because it's in they're stories that they were meant to fulfill that role in society for being born that way, but cursed by Goddess Erishkigal to be scorned by society if they didn't turn to Inanna's help.

So really, it's only monothesism that has a real problem with gays and lesbians not the polytheistic religions that I know of...

And one of the reasons why it may have been that christianity was against homosexuals in the first place was because many priests and priestesses were homosexuals maybe?, and if you want to get rid of a religion or an idea, you aim at the people who are the foundation of it; the priests and priestesses.
