Their Real Beliefs Are the Opposites

Donna: ...Lefitst elite... all for open borders... [yet] promote tribal divisiveness... aspire to One World Utopia... [but] insist on defining and splitting us up into narrowly defined groups

Instead of saying they believe in Utopia, one world, etc, you should say their rhetoric proclaims that, but their real beliefs are the opposites you elucidated.

Which is why I believe the correct term is "regressives."
