Fox News host Tucker Carlson slammed a Black Lives Matter supporter as “demented,” before ending the interview early on Tuesday night’s episode of “Tucker Carlson Tonight.”

Carlson opened the segment by detailing an “exclusively black” party thrown by a Black Lives Matter group in New York over Memorial Day weekend. The organizers asked non-black people to refrain from attending, which led Carlson to ask political commentator Lisa Durden why she would support such an idea.

“Boo hoo hoo,” Durden replied. “You white people are angry because you couldn’t use your white privilege card to get invited.”

Carlson appeared to immediately realize that Durden was fired up, saying “Whoa, whoa, Lisa,” but she didn’t stop and offered to “contextualize” her thoughts.

“I don’t want you to contextualize… you’re attacking people on the basis of their race,” Carlson said before threatening to shut down the interview.

Carlson asked, “If you don’t like people excluding others on the basis of their race… then why are you doing it and why are you defending it now?”

“White folks crack me up… you’ve been having white day forever,” Durden said.

Carlson then went on to label her comments as “hostile” and “crazy.” He eventually asked if it’s racist to exclude people based on skin color. The heated interview continued to grow more and more combative from there.

“You’re demented, actually. You’re sick. And what you’re saying is disgusting and if you were a Nazi, I would say the same thing to you because what you are saying is indistinguishable to what they are saying,” Carlson said.
