Out of everything I said, I'm surprised this is the thing that's contested. Just scroll through his Twitter feed. Here are a few recent ones:

Heck, his Twitter profile pic is a communist logo. His Twitter bio says, "Every loss for a worker is loss for all of us and every gain for a part of the working class is a victory for all." That's a quote from the Industrial Workers of the World[1].

I don't know how much more communist one can get.

Yeah so the IWW is an anarchist organization, not a communist one. Or at least, not a Marxist one. Soooooooooo

Right, that looks pretty clear then. I guess I meant to say that citing his summarizing of Marx is a pretty poor way to suggest someone is a communist, if you can link to something that literally says "I am a communist". Plenty of non-communists cite Marx.

This is 100% accurate. My ultimate allegiance is to Deleuze, but that's only relevant to a VERY small niche of people. Marx is much more well-known.

Also, I care more about left unity than arguing over the exact kind of leftist I or others are.
