Homosexuality is going to self extinguish naturally in a post-abundance world, because the Homos aren't producing, they're waiting for a cast and a fling and a 4v4 pvp sling/slung, and there simply isn't going to be one. If you aren't producing, now you are a net negative on your genes, all that's left is the people who do, heteros.

Alan Turing as an example, is your life improved by computers? Can you have more babies with less effort with computers? Does a trucker with a self-driving truck do more work than the same from a hudnred years ago? Yes, Then the homo catapulted you, you are living in a civilization with homos in it, because it allowed homos to exist and was rewarded for that with the abundance that retarded women need to casually copulate without the net expenditure of effort, thus, homo DNA made you procreate more than you otherwise would have, meaning in you, is homosexual DNA, that didn't express in you, but did express in the one whos behavior prevented a loss. Removal of a negative can be done with behavior, but adding a positive must include the copulation step. Homos can procreate through that naughty porn site I watch you visit from time to time.
