Humans are inherently deeply sexually fluid and the concept of being "straight" or "gay" are essentially lies constructed as a response to the impact of the abrahamic religions. Our closest biological relatives are bonobos for fuck's sake.
As we acquire more information that contradicts the teachings of the abrahamic religions, we progressively abandon those religions, and as a result the grip of their influence over society loosens and humans return to their natural behaviors untethered to the morals imposed upon us by those social infrastructures.

Your grandkids are gonna be buttfucking the daylights out of each other, anons.
