Carlson frequently criticizes immigration. Carlson has been accused by Erik Wemple of The Washington Post and by writers for Vox. com of demonizing immigrants, both those who immigrated to the U. S. legally and illegally. He has opposed demographic changes in the United States, writing that the demographic change seen in Hazleton, Pa. , which saw Hispanics go from a small minority to a majority over a 15-year period is "more change than human beings are designed to digest. " In 2018, Carlson suggested that mass immigration makes the United States "dirtier", "poorer" and "more divided". In response to criticism of this, he has said that "we're not intimidated" and "we plan to try to say what's true until the last day. And the truth is, unregulated mass immigration has badly hurt this country's natural landscape. " Salon has described Carlson's views on changing racial demographics in the U. S. as advocating the white genocide conspiracy theory, opining that Carlson is obsessed with the concept. The Anti-Defamation League's Jessica Reaves has analyzed his use of "white genocide" rhetoric in a 2018 monologue.
