Since 1973, the abortionists in the United States alone have committed genocide on a larger scale than Hitler, Stalin and Mao combined.
Good point.
Er -- give 'em a few years but not yet :-) Mass murderers do not oblige us with good body counts, but I do believe Mao is still number #1. Sanger has moved up to #2, followed (fairly closely) by Stalin. Hitler was kind of a piker in this crowd. The Nazi Holocaust killed perhaps 12 million, half of them Slavs and other, quote, untermenschen, along with the more familiar extermination of Jews. Stalin may have exceeded that number in one winter with the so-called "Liquidation of the Kulaks" -- the forced starvation of the population of Ukraine. (Several estimates put that at six or seven million, but it may have been as much as thirteen million. We'll never know.)
Pol Pot should get some kind of Death Cult award for killing the highest percentage of his country, though he didn't kill as many members of his family as Michael Schiavo.
