I don't actually set out to refute ultra-left and Trot views of Stalin and the Soviet period under him, it just so happens that whenever Hoxha is mentioned claims of general "Stalinist" villany are not far behind. For those who want to seriously defend Stalin you'll need to read books, not just internet stuff but actual library books (academic articles help as well); not just stuff written by fellow Marxist-Leninists but also bourgeois histories, including avowedly anti-Stalin ones.
