Early Dead Kennedys was unique and funny. Black Flag was in no way similar to them. If anything the Dead Kennedys copied black Flag when they got more hard core in their later albums.
I always kind of lumped Black Flag with the Circle Jerks and Fear.
I actually like early Husker Du too- then they got way more commercial and lame. Social Distortion, the Replacements, Husker Du- all overrated IMO.

Rage Against the Machine cracks me up everytime I hear them.

When were they not all Noam Chomsky? That’s their whole raison d’etre.
