You can call them anything you want. History paints them as humanists..People who believed that God was not involved in human affairs or non existent....In other words, they believed in their own philosophy above that of religion......and they have killed more humans in the past century than all religions combined in all of human history.
The numbers don't lie....
History doesn't paint them as humanists, you paint them as humanists.
Hitler:
"Hitler wrote: "I believe that I am acting in accordance with the will of the Almighty Creator:
by defending myself against the Jew, I am fighting for the work of the Lord.." As a boy, Hitler attended to the Catholic church and experienced the anti-Semitic attitude of his culture. In his book, Mein Kampf, Hitler reveals himself as a fanatical believer in God and country. This text presents selected quotes from the infamous anti-Semite himself."
I won't blame christianity though.
