I don't think it's an obvious joke.

In general, you can totally be against the way immigration is handled in one place while being an immigrant elsewhere.

The family you mentioned likely considered themselves different from the immigrants that they complained about.

I'm not agreeing/disagreeing with these people I don't know, but the general point is fair.

I’d be various curious what country you’re from that such people would feel comfortable moving to. But of course don’t share if you don’t want.

> I asked them why they moved here and they answered me straight to my face "Because in Germany there are too many immigrants".

This reminds me of those UK elderly living out their pensions in Spain voting for Brexit to reduce immigration. Thanks to outrage media, I think this public perception of immigration ruining everything is almost everywhere now.

where are you from?
