On the question of Nazis, I must beg your pardon. I know an actual IRL Nazi (or perhaps more), because I knew them before they were Nazis. What I now know on hindsight to be bad faith questions about cultural preservation and immigration was my initial introduction to their new ideology.
On the question of immigration, I think what's being asked for here isn't just modest controls. You might say that, but the language about Germans feeling forced out of their own country would suggest to me that the order of the day is something a little more robust. I think I can be forgiven for that estimation. You can't have it both ways, if you start giving the government extra power to start flexing on immigrants and non-conforming cultures, it's eventually going to get used against you, too. You're never so deep in the in-group as you might think.
