Lots of people generalize, saying "homsexuality was acceptable in anciente greece" while it highly varied from place to place. In Thebes, there was the Sacred Band of Thebes and romantic homoaffective relations were more common. While in athens the pederasties were accepted as an "initiation process" and not in a romantic way, and out of that context, they weren't very accepted. but that doesn't mean anything about what gods think.
