> That’s an extreme take.

Big words considering the rest of your comment.

> If it permits just anyone to enter or exit, it is technically not a nation anymore.

You cannot "permit" something you do not control, so this is a contradiction in terms. If you mean that the constraints put on the US by itself to not police immigration in overly violent or cruel ways mean that it does not control immigration, then by the same logic the 4th amendment implies that there is no rule of law in the US (since certain criminals can't be convicted due to bad actions by the state).

> But being choosy about who gets in and who does not.

Nobody really denies this. The question is how violent or cruel you can be in the exercise of this choosiness.

> Look at the riots in Europe right now

The riots in Europe are not primarily about immigration. Get off twitter.
