After Fox News host Tucker Carlson doubled down on his support of the white nationalist “great replacement” conspiracy theory this week, prominent white nationalists across America expressed glee at what they saw as a possible mass radicalization event.

“This week Tucker redpilled 4 million people and there’s nothing liberals can do about it,” Nick Fuentes, the Holocaust-denying leader of the “America First” movement tweeted Monday night. (Being “redpilled,” or “taking the red pill,” is far-right lingo for adopting a white nationalist worldview.)

VDare, a well-known white nationalist website, gushed over Carlson’s monologue like a proud parent.
