In WWII, the Germans killed 3.3 million Russian POWs, over 10 million Russian civilians, 3 million non-jewish Poles, over 5 million Jews, and a couple of million others. Your comparison with the internment of the Japanese, however wrong it was, is absurd.
"Hitler did exactly what most people would do in his position", you say, and then you come up with a list that isn't "most people". Flawed reasoning, at best.
"Most people under a given government fail to understand that the entire world, every single country, is governed more or less by a variation of democratic socialism much like in Nazi Germany." Most countries don't kill their own and other countries' inhabitants by the millions, nor are they dictatorships, so they are nothing like Nazi Germany.
I'm one of those silly people who have actually done research on WWII atrocities using primary sources. It's always good to get the facts straight before you write something.
