Cognitive dissonance.

Vanishing American discusses the issue of requiring certain people in one country to return to their native countries:

And the [issue] of repatriation, of simply sending people home, is one that has become radioactive in our day, whereas nobody thought it amiss back in 1950 or so. We live in an age of cognitive dissonance as ideas that are declared anathema in one situation are considered good and appropriate in other cases. I suppose, again, it's all about the 'victim' groups versus the 'villain' groups, and the left is writing the script, as always.

She makes the point that now it's instant Speakcrime for anyone who suggests that illegals present in the U.S. should be sent home but, after 1945, for example, no one blinked an eye when Dutch people and Dutch-Indonesian mixed race people in Indonesia were "repatriated" to the Netherlands -- which they'd never seen and didn't want to live in.

Worse than mere repatriation took place, of course.
