Fox News personalities have responded to the revelation that a white supremacist terrorist used language echoing their own in a manifesto explaining the reasons for his attack by defending their use of that language and denying that white supremacy poses a problem in this country.

On Saturday, a gunman massacred 22 people at a Walmart in El Paso, TX. He wanted to stop a “Hispanic invasion” of Texas and prevent the political “replacement” of whites by people of color, according to a manifesto he reportedly posted on 8chan. Last October, another white supremacist obsessed with that purported “invasion” killed 11 people at a Pittsbugh synagogue.

This rhetoric was once restricted to the fringe domains of hardcore white supremacists and conspiracy theorists. But it is now eerily familiar to anyone who regularly watches Fox. The network’s commentators regularly describe migrants seeking asylum or a better life in the United States using the martial terminology of “invasion,” echoing President Donald Trump’s use of the same terminology. And hosts like Tucker Carlson and Laura Ingraham have mainstreamed the white supremacist “great replacement” theory to their audiences of millions of people, while issuing dire warnings about how immigration is “destroying America.”
