Pretty astonishing
The Nazis had to engage in a world war in order to kill people on roughly the same scale as the communists did through domestic "programs." Added to the Chinese numbers can be the millions starved and murdered by Stalin. The balance of blood-letting tips unfavorably against the Marxists.
I don't mean to suggest in any way that fascism "ain't so bad," but you're right, TB...too may of us have given communism a free pass, when its emergence has been, in fact, one of the greater disasters of modern times.
