I don’t think followers of Marx, a self ascribed Satanist, do so for equality. I think it appeals to those that realize (even if they’re too stupid to truly realize it, they do so on some level) it excuses and justifies evil.
FWIW, I dont claim to be a scholar on Marx, or anything but I do know he was revolting against Tyranny. think most blew it out of proportion and it became "communism" as we know it. Dictators and the higher class were starving people. I dont really think he would approve at what others adapted. Communists states are headed by the evil he was opposed to.
