Only good thing Stalin did was to have Trotsky killed.
Stalin did kill a lot of people during his purges. But on the other hand, most of them were commies like him, so there’s that.
Stalin, though one of historys greatest mass-murderers, did at least try to revive the family and put an end to Russias epidemic of crime and debauchery.Toward this goal, he all but put an end to divorce and abortion. Sodomy, pedophilia, prostitution, and homosexuality were criminalized and decrees promulgated aimed at bringing to justice, and punishing with the full force of law, any adolescent older than twelve who is convicted of burglary, acts of violence, grievous bodily harm, mutilation, or murder. Courts were secretly advised that the full force of law includes the death penalty. (The Black Book of Communism, p. 177)
I read recently that Stalin's laws against homosexuality stayed on the books until the end of the Soviet era.
