One is, in a discussion around controlling the behavior of consenting adults, the authoritarians who support telling other consenting adults what consenting adult shit they can get into, again, all among consenting adults, will INVARIABLY fall back on arguments that involve non-consent, or non-adults, or both. I don't care if it's porn, locking up pot smokers, or people exchanging sex for money. Every time.
The other, really goofy sort of "logic" that gets played in these arguments, is the idea that men are all apparently just a hair's breadth away from wanting to abuse kids; really, all it takes is watching a porn with a woman who has shaved, or listening to an evo psych argument, even
and -ZOINKS!- Instant molester!
It's really like the nutty concept which floats around right-wing fundy circles, which says that it is only laws or societal proscriptions against gay sex which keep most men from screwing around with other men.
The REALITY is, statistically, most people are wired to be attracted to adults of the opposite gender. Some, about 10% or so, are wired to be attracted to adults of the same gender. Now, sexuality is a spectrum and people fall all along it, but more or less, that's how normal adult sexuality works.
Then there are the deeply sick individuals who are wired to be attracted to kids. What can be done about them, other than permanently separating them from the rest of humanity, I don't know (hiding in the Priesthood sure doesn't seem to work) ... but there is no "muddying of the lines"; adults, normal adults, are attracted to other adults- and no amount of "programming" through porn or ads on cable or girlfriends shaving, is going to re-progran them to be abusers. Any more than you can re-program gay people to be straight, another conceit of these right wing fundamentalists and their apologists.
