I like the description of Stalin as “rude”.
…he was eventually allowed to enroll at Moscow Uni-
versity (to study Soviet law), but a fellow student denounced him for
“concealing his social origins,” and he was expelled. He then earned a
precarious living by journalism, and was arrested for the first time for
participating in a student movement that demanded (as did many
Trotskyists) the publication of Lenin’s Testament, a document that
named Stalin as too rude and power—hungry to be appointed as secretary-
general of the party.
