First off, nobody takes Marxism by itself. If it’s accepted, it’s always with extra things attached and other parts removed.

What on Earth do you mean? What do people remove?

Second, my issue in this case is the Lennist part. A vanguard party degrades into cult-like behavior, and this is very consistent with ML groups big and small.

What do you mean “cult-like behavior?” Why do you believe this “cult-like behavior” arises? Where does Lenin deviate from Marx?

Why do you advocate for Syndicalism, because it sounds good to you? You aren’t making any analysis nor points, you just seem to be contrarion. Surely you have some reason for wanting syndicalism, no?
