You’re not just “disagreeing with Lenin” (and characterizing my response that way is an obvious strawman/bad faith), you are disagreeing with Marx, and claiming he said the opposite of what he actually said. The only reason I cited Lenin is because he did a very through job of proving you are wrong, using the exact standard that you said you wanted, “the considered and careful words of Marx and Engels.” It’s not as though I’m expecting you to accept him as an authority.
