Are you serious? I’m no social conservative, but labelling that as Nazism just degrades your own political capital.

People are allowed to expect immigrants to fit in.

But it's not just about immigrants. You also forbid people born in your country to develop other habits or change religion.

If a bunch of locals decide to bring back old slaughtering methods (or dealing with spouses or skipping judicial system to settle issues and so on), I'm pretty use that'd be banned in no time.

Well the homogenisation of society is a common aspect of fascist ideologies.

That would be like me calling every lefty a Marxist. It doesn't help.

At the core of every ideology - left and right - are some valid ideas - that is how it got adherents in the first place. A certain degree of social homogeneity is needed because it represents a shared basic idea about how civilization is to proceed.

Now, the Nazis enforced their extreme vision of absolute social homogeneity by means of death chambers... nobody in this thread suggested anything even hinting at that.
