What? Marx wrote EXTENSIVELY on revolution (by the proletariat). It was one of his favorite topics of discussion, and something he was actively hoping for. Have you glanced at, say, his writings regarding the 1848 uprising? His letters to Engels were also absolutely filled with discussions of it. Marx literally and commonly wrote of the proletarian revolution as necessary and inevitable. Hell, he and Engels literally call for the "forcible overthrow of all existing social conditions" in the Communist Manifesto. This is like Marx 101.

And I've met quite a few Orthodox Marxists IRL too, even had a crush on one for a while. I never said they don't exist, so I'm utterly baffled as to why you brought that up. Likewise, I'm pretty baffled by the reference to capitalist circles- were you under the impression that I was one?

Why would I possibly be required to discuss every single group of Marxists, of which there were oh-so-many? For the purposes of this article, ignoring those who opposed the founding of the Soviet Union was perfectly fine, because their opposition failed, and it was founded, and had negative effects on the environment. I can perfectly well call both groups simply Marxists as well and be correct, or use Marxist to describe just one in a specific context and still be correct.

And accusing me of not writing on the concept of marxism- well, I interpreted that as giving me the freedom to discuss a variety of topics, so long as it interacted with the ideas of Marxism. My bad, I suppose.

But... again, your vocabulary test is merely a shibboleth test, not a test of ideas.
