Atheist Governments of the 20th Century: The Death Toll of Godless Goodness
https://www.patheos.com/blogs/publiccatholic/2013/03/atheist-governments-of-the-20th-century-the-death-toll-of-godless-goodness/Mao Ze-Dong (China, 1958-61 and 1966-69, Tibet 1949-50) 49-78,000,00 people murdered
Jozef Stalin (USSR 1932-39 only) 15,000,000 people murdered
Pol Pot (Cambodia, 1975-79) 1,700,000 people murdered
Kim II Sung (North Korea 1948-94) 1.6 million people murdered
Tito (Yugoslavia 1945-1987) 570,000 people murdered
Suharto (Communists 1967-66) 500,000 people murdered
Ante Pavelic (Croatia 1941-45) 359,000 people murdered
Ho Chi Min (Vietnam 1953-56) 200,000 people murdered
Vladimir Ilich Lenin (USSR, 1917-20) 30,000 people murdered
Adolf Hitler (Germany 1939-1945) 12,000,000 people murdered
Now do the millions who have died under capitalist controlled/subjugated countries. Then we can compare to the atrocities of theistic states.
Also seems like you are counting a lot of good murders by Stalin by counting a bunch of dead nazis (who were neither an atheistic state or leftist).
