So on the one hand you chastise liberals for being too puritanical, and then you get upset because a rep called the president a motherfucker? Seems like the “political correctness” boogeyman only applies to criticisms of the right.
I actually agree that the Left should deemphasize identity politics, but that’s because class struggle should take its place. You offer no such critique from what I can tell. This makes me doubt whether you are actually “Left” in any legitimate sense. Taking the easy Dave Rubin route of complaining about “those crazy leftists” is pure reactionary politics unless you couple it with something substantively left-wing.
