Late-night show host Bill Maher railed against social justice warriors on his HBO show, calling them a "cancer on progressivism."

He also insisted that "cultural appropriation" doesn't exist and shouldn't offend anybody.

What else did he say?

Maher addressed progressivism, cultural appropriation, and more in a discussion with author and Commentary editor Noah Rothman during Friday's airing of "Real Time with Bill Maher."

During a panel discussion, Maher argued that social justice warriors don't actually believe in justice.

"I talk about it here a lot, that there is a, I would say, a cancer on progressivism with some of the, I guess they call themselves social justice warriors," Maher explained. "I don't think they are interested in justice. I don't think they're interested in truth. I think they're interested in clicks. I think they're interested in things that make people click. And when I read them, it makes me glad I didn't have kids who would see this."

Rothman, who wrote the book "Unjust: Social Justice and the Unmaking of America," added that it is a "noble idea" that became "antipathy towards notions like meritocracy."

"[S]ocial justice is a noble idea," Rothman answered. "It is the idea of fairness and equality and a just society. In practice, it has become antipathy towards notions like meritocracy, like you can rise above your station in life, or color-blindness in institutions. White supremacists believe all this stuff, too."

Maher went on to address cultural appropriation, which he said doesn't exist.

"I feel like that's something that was just made up," Maher said. "No one is hurt by cultural appropriation."

What else?

Also on the panel was former GOP Chairman Michael Steele, who said that the key to determining whether cultural appropriation is offensive is "how you use it." Steele brought up former local NAACP chapter President Rachel Dolezal, a white a woman who posed as a black woman.

"When a white woman goes around the country and says she's black and her white parents say 'No, she ain't,' and she keeps insisting that she's black, that's just bull and we don't like that kind of cultural appropriation," Steele said.

Rothman offered his own argument, and pointed to the news story of two women who were "hounded out of business" after they used an authentic Mexico recipe for one of their menu offerings.

Maher later added, "These people just want to bitch."
