It must be incredibly frustrating to be told you are not X.

How to reach them, then? Should one even try?

If the US went to crap and I was able to move to Australia or New Zealand or France or UK, I think I would. I actually think the flow of people from worser places to better places is a feature, not a bug. That it provides a great deal of useful feedback in the world, and reallocates human resources to places where they will be way more useful and possibly happier as well. But it is a personally painful thing for the individual to face.
