> children getting fucked up by hardcore porn

What evidence do you have that this is a reasonable concern?

I've seen plenty of hard-core porn since the age of 10 and turned out just fine. I don't know anyone in my generation that has said otherwise.

I know plenty of lifelong smokers who lack cancer, so it’s fine then?

In any case, if we’re to share anecdotes, I don’t have a single man I know that has said “wow, pornography has enriched my childhood / adult life.” I know plenty that have had trouble in their relationships, however.
