Actually, the number of people with homosexual orientations growing has been seen in other species especially with pollution or other new chemical interferences into their populations. In my opinion, the acceptance has come due to the sheer numbers and not the other way around.
I agree, fetishes come from imprinting and brain damage such as autism. You can’t be born craving 4 inch high heels to have sex with. Check out little autistic kids who crave spinning wheels or rolling a certain ball. The need for a certain object or mechanical movement. It’s definitely a warp in the brain.
One thing the LGBT community got right was that they all belong together lumped into in the LGBT because the sexual orientations and gender identities are interwoven and must come from a prenatal epigenetic defect.
Well, either that, or the queer child-molesters got to them, just like it’s always been.
