This is about Romani communities that have been living in the same place for generations. You can't legally deport someone who's a citizen from birth no matter what ethnicity they are.

And even with actual illegal immigrants there's a different between saying a country can deport them, should deport them or has to deport them based on some bizarre fascist ethics.

I have no problem with people who don't like immigration and want to send them back (I just really don't agree with their opinion), but DHH is closer to the last group. He's saying that each country has a moral duty to deport immigrants and every individual citizen has to support that, and if they don't that means they're evil and want to destroy their own people.

Using violent language is just a cherry on top.
