I think the most damning thing about porn hysteria is that society as a whole ran the experiment of an open internet for 30 years, long enough for a full generation of people to be fully raised on it and -none- of the things the anti-porn crowd cried about came true. In fact things actually moved in the opposite direction. The whole think is unsurprisingly just as bunk as the hysteria over violent video games and "demonic" music.
It seems plain old social media is the actual damaging thing to come from the internet.
