Porn has actually helped lower the amount of rapes, sexual assaults, etc. The National Resource Center on Domestic Violence backs this up. Religious ideologies, not reality, drive the anti-porn agenda. Studies show 77% of Americans view poronography at least once a month. At the same time, sexual assault has decreased by 45% in the last 20 years. With population adjustment, that number shows a decrease of 55%.
Is there a slippery slope of watching too much porn? Of course, but it looks like that is more likely to lead to decrease in sex drive and ED than in sexual assault. There are more and more studies coming out that show overconsumption of porn by young people decreases sexual libido and is increasing cases of ED in men under 40. One out of every ED patient is now under 40.
