I agree that the addiction to pornoghraphy is a serious issue in our time. However I can't agree that the government should have any say in the matter beyond legislation to keep it out of the hands of minors. I see sense in much of the legislation being brought forth i.e. requiring filters on computers in Public Libraries to limit their ability to access porn, yet I am still a firm believer in what a person does behind closed doors,(and don't get all indignent and make stupid statements about abusing kids and farm animals) is none of the governments bussiness.
If a guy is so addicted to porn that his wife leaves him then he's a sick foolish man and probably needs to be left. If however a man uses porn to feed his sick fantasies until he finally breaks and commits a horrific act then he is, was and always would have been, regardless or his use of porn, a sick dangerous man that needs to be locked up and get secluded from the rest of society.
