Wow.... That’s a lot to words to say: “They Can’t Reproduce, So They Have to Recruit”.
Yes, perhaps it’s simple as the “Survival of the Fittest” where as a homosexual gene is produced due to a poor genetic profil that ‘nature’ sees as not worthy enough to breed or pass along as a human. In other terms; “To stop this ingrate from making humans like him, we’ll make him like males only and eventually his type will fade away.”
Too simple?
