It isn't even obvious that "identity politics" is tethered exclusively to left-wing politics. Plenty has been written about the group of people that invaded the Capitol last year, and the only consistent characteristic of that group was being white. No, it has nothing to do with economics. It included a doctor making $ 650,000 p. a. as well as a group that traveled to DC on a private jet.
Hell, the major group of young reactionaries in Europe (until recently) had "Identity" in their name.
This text just seems entirely out of place, and I was wondering if I missed the (2008) in the title while reading it. There's nothing new in it, and it wouldn't get much attention if it weren't for the name.
