Re: kids raping kids
PCG - I believe it to be the opposite. The tendency resides in a rapist therefore he would watch porn along those lines. The porn doesn't create the problem, the problem was there all along. If you, Joe Blow on the street, and I watched violent porn, we would more than likely turn it off or turn away for one reason or another. But a person who has the tendency to rape would watch and enjoy.
A lot of people I know who tend to Dominate would also never rape. It has to do more with abasement and humiliation than actual Domination.
