The issue of one or more supreme beings hating homosexuals is a belief held by the followers of a number of different religions, though, it should be noted that, at least for some Christians, it is the 'sin' of homosexual behavior that is hated, not the individual who is engaged in homosexual activity.
My own background is Christian, specifically Roman Catholic, and this is the Faith system with which I am most familiar, so I'll leave it to others to address the beliefs regarding homosexuals in other, non-Christian Faiths.
Essentially, because the afterlife, specifically the destination of one's immortal soul, is considered within Christian teaching to be more important than one's temporary existence here on earth, our sensual desires are less important than ensuring that our immortal souls earn a place in heaven rather than hell.
Christian teachings assert that the temptations of sensual desires must be resisted in order to earn a place in heaven because acting on one's sensual desires is believed to be a sin. However, this presents an obvious problem. Sex is necessary for procreation, yet Christianity professes that sex is a sin that will interfere with one's ability to enter heaven. This is why sex for the purpose of procreation within the sacrament of marriage is not considered sinful within Christian teachings. Indeed, Christian teaching celebrates the bringing of new human life into the world as a blessing by God.
Therefore, most Christian denominations view homosexual behavior as sinful because it involves indulging, rather than resisting, one's sensual desires, specifically sexual desires, that are not for the purpose of producing children.
Please understand that I am attempting to explain the basis for the condemnation of homosexual behavior by most Christian denominations. I am not advocating for or against these beliefs.
