Not to troll here, but Hitler and Stalin were both atheist AFAIK.
Christians are eager to mod you up even if your claim has no base in reality. That's so typical of religious folks.
Hitler was Christian in his public life. His mother and father were Catholic, but he personally identified more with teachings of Martin Luther. Maybe this was because Luther had very anti-Jewish views. In his book Von den Juden und ihren Luegen (On the Jews and Their Lies) Luther described jews as:
"base, whoring people, that is, no people of God, and their boast of lineage, circumcision, and law must be accounted as filth."
Seems like Hitler found a soulmate in Luther.
In Mein Kampf Hitler wrote:
" The folkish-minded man, in particular, has the sacred duty, each in his own denomination, of making people stop just talking superficially of God's will, and actually fulfill God's will, and not let God's word be desecrated. For God's will gave men their form, their essence and their abilities. Anyone who destroys His work is declaring war on the Lord's creation, the divine will. "
Those aren't words of an Atheist, are they?
