Acting like a Christian makes one a Christian?
If by acting you mean also enganging in attempts at understanding the doctrine and following it to the best of their abilities, then I suppose that yes it does.
Have we ignored the fact of propaganda?
How do we measure it in this case?
Courting the churches in Europe makes sense because of the power base they provide with State sponsored religions. To assume that is genuine simply because he said things in public is naive.
Yes, it is. But that is a very slippery slope to thread. Besides, it is also largely irrelevant. Any number of political leaders may turn out to be insincere believers deep down, but we neither have a way of truly knowing nor do we have a reason to disregard the actual religious wrappings of their leaderships.
As it turns out, Hitler very explicitly claimed to be acting in harmony with God's desires time and again, in the Mein Kampf among other places. I'm not sure what else could we desire to conclude that he was indeed a Theist - and more significantly, that
his leadership depended on Theistic beliefs to reach so far as it did.
Every statement Hitler made in regards to Christian faith was made either when alliances needed to be cemented or speeches. Hitler saying he would always remain a Catholic was in discussion about cementing relations with German Catholics.
That may well be true, but what does it show? Were there even any times that did not fit that description?
As to Hitler's Table Talk only Dr. Steigmann-Gall is the one who claims it isn't legitimate and with rather flimsy reasoning. Of course his research is largely based on the Positive Christianity movement initiated by the Nazis and thus I feel his research blinders have creeped in with Hitler. He offers much more legitimacy to Hitler's public speeches and commentary than his inner circle dialogues.
As arguably he should, even if that might shift the matter of our interest from the importance of Hitler's own personal beliefs to those of German people as a whole.
The biggest reason Steigmann-Gall claims it isn't real is bizarre as well since he states that it was simply hand written accounts.
There is also a question of how faithful the translations into French and English were. As well as how much Bormann allowed the text to be faithful to Hitler's intent.
Yet if Steigmann-Gall was as familiar with Hitler as he was Nazi Positive Christianity he would know Hitler was utterly paranoid about recording devices in regards to personal conversations. Thus with Steigmann-Gall's reasoning you could reject anything Hitler said privately. Yet Steigmann-Gall accepts anything reported second hand and in line with his thinking as legitimate.
If you concede that much, then it must follow that Hitler's Table Talk is unavoidably unreliable, despite your earlier statement that it was definitive in proving that Hitler was a non-believer.
I fear he has fallen into confirmation bias. The book does have translation issues but those quotes were never my bias for my opinion. Hitler always had a respect for Jesus Christ but not as a messiah of any sort but as a fighter against Jewish corruption. There are also claims that Martin Bormann Hitler's personal secretary was part of the Red Orchestra ring and thus his obsession of keeping recordings of personal conversations. The reason this claim still bounces around is for the fact that we do know the Soviets had an inside man in the Bunker and Bormann completely disappears shortly after Hitler's death. Though that is mere circumstantial evidence and it could be just as likely Bormann was just one of countless many dead in Berlin at that point.
Now would I personally call Hitler an atheist? No the term doesn't fit his views of the world. Hitler had an idea of divinity but it doesn't fit any traditional religion. He makes references repeatedly to a divine mandate for racial warfare and an idea that the Germanic race has a special place in history. Which is somewhat similar to ideas espoused by Martin Luther as well. The problem with Hitler as I highlighted in my previous post is the man put up so many fronts for who he was I don't know if anyone really knew the man except for maybe Eva Braun.
Myself, I think he was just a paranoid nutcase with some talent for speeches and a rather mediocre overall intelect. Unfortunately, he happened to live at just the right time and place for that to be disastrous - but he is hardly the unique, irreplaceable kingpin of disaster that so many seem to hope he was.
