how many dart generations are there?

I think the Dart Sports were all Demons. The "Moral Majority" made Chrysler knuckle down and drop the Demon name and symbol. Otherwise those Dart Sports would be Demons.
Dodge Dusters, just like Scamps were Plymouth Darts.
I'd label a Scamp a Dart before I'd call a Dart Sport a Dart.

If your talking about the organization, 'Moral Majority'......it wasn't founded until 1979......long after the Dart was out of production. If you're talking about a bunch of 'preachers' complaining about the 'Demon' moniker, I'll agree with you there! Ben.
