Once I saw Jack say "you don't seem to know what 'neoliberal' means," I knew exactly who he was talking to. VivaRev is a mid-century conservative (that is, someone who is superficially supportive of unions and ambivalent to trade, but opposed to everything adjacent to and important to workers' interests and the interests of exploited people and basically anything that requires substantial thought or reconsideration of powers, yet somehow thinks himself a socialist class warrior.
I used to give him a little bit of a pass, or at least try to, on the basis that he means well, but it's getting harder and harder to do that as he continues to align himself with right-wingers that he knows are exploiting his emotions.
