I cannot say because I was not there, but my mother grew up in Vienna during the 30s. Her family was not Jewish or any minority - in fact, they were aristocrats - but they all picked up and moved to Brazil to get away before the Nazis came in. They wanted nothing to do with the Nazis.

My mother's step father was a pilot, and got a job in South America for an airline, but the Nazis down there found him and demanded that he return to Austria and fly for the Luftwaffe, but he refused, and so they murdered him.

My impression - which I cannot rely on except as heresay from my mother's tales - is that Austrians were divided: just like in the US today, some embraced the law-and-order right wing populist movement, while others rejected it. But since the right wing movement were carrying machine guns, and could murder people without consequence, those who disapproved kept quiet.

One cannot blame those who embrace a populist hero who makes promises. People just want their life to be better. But sometimes people cannot see through lies, and are too ready to accept scapegoat narratives.
