Depends what the post-punk description is getting at. If it’s speaky/shouty vocals over a bass line with little melody, intended to summon the spirit of PiL but in reality presiding over its corpse. then I’m with you.
If it’s “angular guitars” (world’s least helpful description) over a driving rhythm section (a la Bloc Party), something in the vein of the Banshees, then I’m going to have to politely disagree.
