When some grew suspicious and made their concerns known, the Nazis simply mowed them down. Those of us who were born shortly after WWII never got to see Hitler when he was an up and coming politician. We got to see what was left in his wake, our father's nightmares from the horrors of the war, their tears at the overwhelming losses.
Up to that point, Hitler was a swell guy and great dancer. No one EVER thinks it's the devil when he has his arm around your shoulder and speaks words of comfort and enticement.
It doesn't denigrate results of the historical Hitler. It reminds us the devil is in the details and all hooks are baited with something enticing.
EVEN in America there was a hush hush police on denouncing Hitler (prior to our entering the war).
Hollywood was afraid that they would lose a sizable foreign market (and people TRIED to make anti-Nazi films going back to 1936).
And Communist Party USA stood with Mother Russia (which has signed a pact with Hitler) in denouncing any move for the US to go to war againt Nazi Germany.
Sadly, I think these points are lost on the dear deacon who runs the blog, along with so many others in the clergy that do not understand that the Christian principle of self-determination is the cornerstone of Western society.
