Quote from Petsamo:
Sorry for not backing up my claim.
In this article, "the incidence of rape in the four states having the least access to the internet showed an actual increase in rape [but] in four states
having the most access to the internet, three out of four of these states showed declines (in New Jersey, an almost 50% decline)."
There are plenty of articles on the internet, just Google "internet pornography rape".
Suppose we correlate internet porn and rape of of women over age of 50, and check the results. How about internet porn and fathers and brothers who rape sisters and daughters and see if their is a decline.
