Joseph Stalin -- the Stalinator

The Man of Steel is back to smash Trotskyism, Cosmopolitanism and Capitalism!

Bye bye Trotsky and modern fake Leftists! Look at
our black soviet boots, postwar punks! Joe Stalin is back! Trotskyites and anarcho-marxist punks will soil their pants! The modern Left is a joke! HAIL STALIN! ICE !!!

Are you ready for a REAL STALINATOR?
A REAL REVOLUTION?

If you are a phony postwar "Leftist" and think Nationalism is wrong and there was no difference between Stalin and Trotsky or your cosmopolitical bullshit, be careful what comments you post because if they're childish or stupid, they WILL be deleted. I'm left-wing, what are YOU?
