The problem is banning something also affects those who do not have a problem which in this case most likely is the overwhelming majority.

I'm raised with internet porn and I don't believe I have a problem. Why should I be banned from watching something I enjoy?

I don't buy the crap about porn changing people. Sure you can say that for yourself if you got addicted but you can't just throw that out as a general truth. Porn has been around for a long time now and I don't really see people behaving different today.
