No, we weren't.
My own family was German, and was only terrorized when the Germans drafted my grandfather and his brother. On the threat of sending them to the concentration camps if they refused, along with additional reprisal towards their family left behind.
Also ou can try and give me name of one (1) ethnic German "terrorized and killed" in the months or years before the war. Which you can't, because nothing like that was happening. It's possible you might be confusing the Sudetenland provocations in Czechoslovakia with Poland now (where there was only an Ukrainian insurgency, plus Communist troubles).
