Psychopaths existed before porn, exist during porn and will exist after we cease to become sexual entities. As someone who posts on a gaming site, you should know the issues with this argument -- it is the same one used to argue for banning violent video games, because it supposedly turns people into mass murdering psycopaths. We've all killed thousands of thousands of pixels in TW games, inflicted all kinds of violence on people in games, and does it make us any more or less likely to kill? No. People who kill others out of psycopathic tendencies are psychopaths, plain and simple -- they will be psycopaths with or without outside influence. Jack the Ripper had no porn to 'pervert his mind'.
