The inhuman character of Stalinism was demonstrated by the repressions of prisoners of war who survived fascist camps and then were thrown into Stalinist camps, the anti-worker "decrees," the criminal exile of entire peoples condemned to slow death, the unenlightened zoological kind of anti-Semitism that was characteristic of Stalin bureaucracy and the NKVD (and Stalin personally), the Ukrainophobia characteristic of Stalin, and the draconian laws for the protection of socialist property (five years' imprisonment for stealing some grain from the fields and so forth) that served mainly as a means of fulfilling the demands of the "slave market."
