I think he was using the word "sane" loosely to mean common people, not a niche group. I agree though that it's hypocritical to label some sexualities as a disease or insanity but object to doing the same for other minority ones.
are you actually trying to say that being a pedophile is a legitimate sexuality?
or even that it's anything like being gay?
That's an interesting question for which you'll get no answer for reasons of force majeure.
just curious: are you comparing being gay with being a fucking pedo?
