////On the one hand, josepp's statement that Stalin and Mao replaced the concept of God with themselves (and their political system) is quite correct. On the other hand, josepp's statement does not fairly address what Jack said about officially atheistic (meaning anti-God) governments committing atrocities just as heinous as theocracies do.////

Actually I did. I said that it is immaterial whether any such atheistic govt has ever existed (which I do not believe to be the case and perhaps you could enlighten us if there ever was one), Stalin and Mao do not represent such a govt.
