The statistics on rapes come from the Justice Department. The Ashcroft Justice Department, by the way.
As for porn being more mainstream, I don't know how anyone can deny that.
You don't need to prove anything, unless you want to insist that porn "causes" rapes. That was the clear message I got from a prior post of yours, but I am willing to admit that I may well be mistaken.
So let's clear the air - I do not believe that there is a connection between access to porn and propensity to rape. I have seen no evidence to support that position, and plenty to contradict it.
Do you believe that porn causes rape?
I've never understood how pornography (sexual stimulation) can be related to rape which we're told is not a sexual crime but a crime of violence (subjugation). I guess if the porn is nothing but violent S&M, simulated rape stuff.
Causes? No. Given the above, there may be some connection if the type of porn focuses on it. My guess would be that the person is predisposed, rather than being "converted" by the porn to a rapist.
I used rape as an example because the author made the connection. I'm not hung up on it. Any negative criminal behavior associated with porn will do to make my point.
And that was, in my opinion, I'd rather arrest the pornographer than the criminal who comes about because porn is legalized..
