Simple, no balls.
I have to disagree with your contention that they are marxist.
Marx envisioned a “classless” society (as in social class, not “classless” like Springstein), these people want a 2 class society, a ruling class and a slave class, with no mobility between the classes. Either fascism or socialism could get them to those ends. They seem to favor the fascist route (private “ownership” but govt control of the means of production).
