DNA variants linked to gay sex also appear more in straight men w larger number of partners & w greater attractiveness. Variants may “confer a mating advantage to straight carriers” which helps explain evolutionary persistence of gayness. https://www.technologyreview.com/s/611946/genes-linked-to-being-gay-may-help-straight-people-get-more-sex/?utm_campaign=social_button&utm_source=twitter&utm_medium=social&utm_content=2018-10-18 … | @techreview

Yes, that's not an rg. However it's an example of a situation that's very difficult to "disassociate" for natural selection. Of course eventually there will be modifiers. Yet Sickle Cell persisted for how long with an disadvantageous phenotype?

Only ~10kya, IIRC. Homosexuality has probably been around way longer.

complete conjecture

It's not like we don't see plenty of homosexuality in other primates or the animal kingdom. Is there any particular evidence that homosexuality is a brand new thing in human history which only showed up recently?

I would like to see reliable sources about prevalence of homosexuality in animals besides sexual imprinting or being so horny you f** everything that moves.
-
Homosexuality in nonhuman animals, maybe sans primates, is mostly a failure mode of mate choice
