> I pointed out that there was quite a lot of government involved in this decision, referring to the well-known history of certain WWII fascist dictatorships in which the entire society was effectively subjugated under the authority of a single person.
You're completely ignoring how the dictatorship came to be. Hitler didn't just step off a spaceship from another planet and immediately become leader of Germany. There was a democratic government for many years before he came to power, and the Nazi party spent many years gaining political support during that time. In 1932, they won 37% of the vote, becoming the largest political party in the country. The people who voted for them were going down that path voluntarily. You seem to be taking the existence of a dictatorship for granted, a fact without any need of historical or causal explanation, as if nothing that happened before 1933 mattered.
The Nazi party was explicitly racist, explicitly antisemitic, explicitly anti-immigrant. And they were popular! So yes, this was local people getting together and deciding to form a tribe based on hatred of others.
