In pbs-eons tier history of the upright vertibrate biped, every 7 years, almost without fail, there was a food famine, there is not enough food for everyone to survive, because the trees didn't produce melons that year. As a result of this shemitah, there was a selective pressure for males who for whatever reason assembled into troops of other males, because they like it. As the famine hit, only these homosexual men have food, and all the starving females from other troops, would stand up, and mate with the homos because they had food and the Alpha Male Inidivudal heterosexuals simply collapsed having not eaten anything in a month.

As a result, homosexuals are selected into the population because of their desires and their behaviors. Today this selective pressure is diminished, but it takes at least a million years for something that has worked, without fail, every seven years, for the last billion years straight.

You don't like it, because homos slow evolution down, you need to make babies. A male that doesn't try to produce is wasted calories. And so you are inflicting the simulation's calculus on that game theory 4 of multiple multi-engine universal engines on said self replicating site to site transport system.

If you don't like it, you say: "My angle is non-famine", I see you optimize for shemitah and famine, but that's just not me, can't you see.
