Fact, every single german nazi was a christian

[Cephus]

Actually, while Stalin did, indeed, persecute the church in the early days, he also reinstated the church and used it quite extensively for political purposes.  Of course, the religious aren't usually aware of actual history, they have no clue what their own religion has done and even less knowledge of the world outside of it, they just go by what they've been taught from the pulpit.

Indeed, but it's fair to say Stalin reinstated tolerance for the ROC for cynical reasons; the country was being shattered by German hammerblows in 1941, and the government needed support from every quarter of civic society.

It doesn't matter why he did it, it only matters that he did it.  The religious don't want to acknowledge that, or aren't even aware of it, because it interferes with their oppression narrative.
