Great article, and I agree with almost all of it. The people you’re describing are the Alt-Left (which is now, ironically, the mainstream Left), not the Real Left (the Bernie Sanders wing):

The one point I’d take issue with is this:

The modern liberal will squeeze every last vote out of racial identity politics that they possibly can, but try getting them to sign on to the notion of taking some actual money away from the plutocrats and the war machine and putting it toward slavery reparations and see how fast they slam the door in your face.

The whole “slavery reparations” thing is just another regressive attempt to sow racial divisions to ensure poor and working-class whites and poor and working-class blacks stay perpetually polarized and unable to form any sort of political coalition to oppose the NeoLiberal/NeoCon kleptocracy. It is no accident that slavery reparations were injected into the mainstream conversation by that ultimate black NeoLiberal lapdog, Ta-Nehisi Coates, who, as I’ve argued, having probably done more than virtually anyone else to bring racial identity politics into the mainstream, has, as a result, played by a big role in driving the resurgence of white identity politics:

I think every time the Alt-Left and racial identity-mongers start talking about reparations for slavery, the party of Steve Bannon gains a few more followers.
