Read my post again. You addressed none of it. There was no recommendation there that you or anybody else should tolerate or participate in homosexuality because many of the beasts do.
And I don't live mine by what ancient holy books advise. The god of Abraham is a bigot as depicted - homophobic, atheophobic, and misogynistic, condones rape and slavery, and considers human wisdom foolishness and scripture wisdom. We can do better than that, but not if we let sources like that one inform us.
And has been mentioned, we are all animals, and have most of the same drives. They don't all serve us in civilized life like they did when our ancestors lived in trees. Now, we need to develop rules about killing in anger and taking what isn't ours, for example, to preserve social cohesion and peace.
Humanism takes that further, and fosters human development and maximal social and economic opportunity for the greatest number to pursue happiness as they understand it within the confines of those societal rules. The bigotries of the Abrahamic religions are counterproductive to that end, and thus immoral. They make many lives worse.
Like I said, we can do better than that, but we need to shake the toxic influence of such religions, or, at a minimum, keep them out of the lives of unbelievers, who don't care what the faithful think their gods want.
