What? There's zero suggestion in ndriscoll's comment that he's talking about "extremely violent porn".

The most specific he gets is "furry porn", which might be a kink you don't approve of but is not obviously more objectionable than "people having sex".

I made a mistake about who stavros was replying to. I edited my comment.

I was being somewhat flippant while also using a group that's known as a gateway to more deviant behaviors (e.g. libertarianism). I think though that you'll likely not find much success in litigating whether children ought to be able to access porn (and whether porn has anything close to a healthy depiction of relationships/sex. Yes, some healthy material exists. It's extremely rare, especially with commercial websites). e.g. no one thinks children should be able to shop at physical adult stores. It's probably more productive to participate in the "what to do about it" discussion.
