> Do you really think Haidt is lazily missing a causal link here?

To be honest, no.

It's not lazy, the platform he's writing this has the tagline 'Using moral psychology to explain why so much is going wrong', so morality is at the center, and at the start of his essay he goes "I think it is a very good thing that alarms were rung about teen smoking, teen pregnancy, drunk driving, and the exposure of children to sex and violence on TV.", putting smoking, teen pregnancy and actual homicidal behavior at the same level as fictional sex and violence.

I think he's not even playing dumb, and purposefully chooses arguments he has no incentive to properly research, or straight omits the other probable causes he has knowledge of.
