Michael Palin's series on Nigeria highlighted similar points and is well worth a viewing.
While religion is often aired as the key cause of such loss of life and/ or dignity, atheism reigns supreme, certainly throughout the 20th Century. It's interesting that atheists routinely urge that the Nazis were Christian, invoking Christianity to justify their horrors. This is false. Nazism and fascism never held themselves out as Christian enterprises. More particularly, Hitler himself despised Christianity. He saw Christianity as “meek” and “flabby” and sought to destroy it “root and branch”. He bemoaned why Germany was “stuck” with “feeble minded” Christianity and preferred other “strong-arm” systems. Hitler’s writings and speeches are so full of passages dripping with contempt for Christianity that to argue he was Christian is like arguing George Washington fought for the British during the Revolutionary War.

5 uncomfortable facts atheists need to hear
The most common argument is that atheism is not an ideology; it merely reflects the absence of faith in religion. They just don’t believe in God. Why can’t we please leave them alone?
But it turns out they don’t want to leave you alone. On social media most atheists are bizarrely vocal about their contempt for Christianity and, to a lesser extent, Judaism, for their beliefs. They believe these religions frustrate progress. They argue with great passion that we’d be better off if we just eradicated God once and for all. Godless regimes have always sought the eradication of God with passionate zeal, deadly efficiency on a mass scale, and unspeakable cruelty.
Such thinking is an ideology. Such “non-belief” has devastating consequences. Not believing in God is like not believing in seat belts. Or better yet: it’s like not believing in the police, the judiciary, medicine or fire stations. You don’t have to believe in them, but living in a world without them has consequences:-
Not least the top five on a list already mentioned in this discussion - all atheists:-
