You bring up a good point in #2
It's (mostly covert) sexual suppression, through media, education, religion, parental upbringing, etc. that causes the bulk of sexual deviants. It's not natural to feel shame for one's sexuality or sexual preferences, yet western society seems to place extreme emphasis on slapping wrists for having sexual thoughts/ feelings.
It's the same with many of the extremely religious types. Anything that we're inclined to be attracted to, out of our very nature, they treat it as if it is evil/ sinful. It's a massive, nearly world-wide, case of self-sabotage!
It's actually gross.
I totally Agree!
They are indoctrinated to suppress natural sexual desires and attack try to censor anything even remotely sexual. Yet Globally it's proves they are doing more harm than good.
