I've been called a tankie for lots of reasons: criticising Elon Musk, condemning Israels genocide of the Palestinians, opposing invading Venezuela, condemning the US's destruction of North Korea, not believing that far right American think tanks are trustworthy, calling Kamala Harris a genocide supporter, calling bullshit on the claim that Mao had one in ten Chinese citizens executed for being a western spy. Calling bullshit on the claim that Che Guevera committed genocide. Basically anything that runs counter to the average American neo-liberal's world view.
