Not sure how many have read "Mein Kampf," but in it, Hitler states that he once considered the priesthood as ideal, but later changed his view to embrace Luthernism as better (probably because if its distinct Germanism).
Plenty of Catholics died in the cσncєnтrαтισn cαмρs (none by gas, of course).
I would be open to hearing any who can reconcile that fact with the portrait given in the OP.
Not challenging it, just asking for an explanation.
As an aside, there is no doubt that Hitler was a military and economic genius: He dang near won a war being fought on two fronts (three fronts, if you count Africa/Italy/South).
