>>2033I have no idea, I'm not sure if anti-idpol punk is a thing.
I guess maybe Future of the Left could count, I forget if they've addressed idpol specifically or not, iirc they have a song kind of satirizing it… and their general outlook seems to be cynical.
There are also the olden Redskin bands like Angelic Upstarts who dealt in class politics. I don't like them as much as I used to, 'cuz they were anti-USSR during the Polish crisis (seems like an op in retrospect), but they aren't very idpol-y afaik.
