If i was going to prove porn was actually helpful i'd look at Japan. They have whole series on Rape-related porn and games. They have like the lowest rape-rate in comparison.
There are like a million factors which are involved in the rape-rates. If porn was a factor, it is a very, very, small one.
There are two types of tragedies in life. One is not getting what you want, the other is getting it.
If you wake up at a different time in a different place, could you wake up as a different person?
