I think whatever Nazi Germany was, Christian or non-Christian, it was certainly religious and theocratic. It was a political system so rigorous that it was like a religion, with Hitler basically being worshipped as above human and infallible. It's the exact same with the Stalinist and Maoist regimes, they were not "atheist" states because the leaders were revered through propaganda as basically gods. You could say nothing about them that was negative or you'd be punished like a blasphemer in Saudi Arabia would be. Same with North Korea, I could go on.

"Ironically like the nativist far-Right, which despises multiculturalism, but benefits from its ideas of difference to scapegoat the other and to promote its own white identity politics; these postmodernists, leftists, feminists and liberals also use multiculturalism, to side with the oppressor, by demanding respect and tolerance for oppression characterised as 'difference', no matter how intolerable." - Maryam Namazie
