I have not called you racist anywhere in our conversation. I've simply asserted that a policy may be discriminatory.

I also don’t see how universal human rights leads to “nation-states should not exist". A state can have borders, put limits on immigration, and prioritize citizens while still being limited by due process, equal protection, and non-discrimination.

The part I'm against is treating individuals as suspect mainly because of group averages, nationality, ethnicity, religion, etc, rather than their own conduct.

If your position is just that states can favor citizens in some respects, I think there is no argument there. Where I disagree is with using that rationale as a way to justify broad disfavor toward legal residents or non-citizens as an entire class (whether administratively practical or not).
