I think that's unduly reductive. He seems instead to be saying that if you were abused in the 80s, you should just get over the thought of people watching footage of it today for kicks.

Which is an interesting viewpoint, to be sure. I wonder whether he'd say the same to an adult victim of rape whose abuse was videoed and passed around for other people to get off on. That's a pretty close parallel, but it never seems to turn up in discussions like these, and I wonder why that is.

It seems to me that distributing such videos would have far more in common with defamation than with the original abuse. Merely having or watching them... is probably bad and wrong but not something that ought to actually be legally punishable.
