LAURA'S NERVOUS AND THE LIGHTS ARE BRIGHT (profanity alert):

It wasn't so much a dog whistle as it was an airhorn. Or perhaps a primal scream. But whatever it was, Laura Ingraham's forceful denunciation of "massive demographic changes" served as another raw example of a Fox News host echoing white nationalist language.

Perhaps it was a glimpse into President Donald Trump's well of support, too.

The Fox News audience is almost 100% white, according to Nielsen. And on the channel's highest-rated shows, the politics of white anxiety play out practically every day, as hosts and guests warn about the impacts of immigration and minimize or mock the perspectives of people of color. The talk show segments are clearly intended to appeal to people who perceive they are losing their grip on power.
