DaasYochid: That only makes sense if you think chassidus was invented, not if it’s just restating what’s already in the Torah.
In that case there should and should not have been any disagreements about Chassidus. [And if you mean to say that the parts that the NH writes like Chassidus is not because he takes it from them, rather because it is pashut peshat in Chazal, In that case you missed my point. The NH interpenetrates many passages in the same context as Chassidus, where it is not found in any other source only there.]
