Conservative commentator David Horowitz caused some controversy today with a Breitbart article whose headline labels Bill Kristol a “renegade Jew” for supporting a third-party alternative to Donald Trump.

Such rhetoric is nothing new from Horowitz, who in an interview today with Pennsylvania talk radio host Bobby Gunther Walsh about his new book, “Progressive Racism,” claimed that any member of the Black Lives Matter movement who calls the U.S. a “white supremacist nation” is a “stone-cold racist or a lunatic,” as proved by the pervasiveness of hip hop and the financial success of some NBA athletes.

“Black people have been accepted; not black criminals, but black people generally,” he said, citing former GOP presidential candidate Ben Carson, President Obama and others.

“Our culture is dominated by black music, if you can call that music,” he added. “Hip hop is the dominant music form, more than any other, and it pervades the white suburbs.”

“If it were true that a racial disparity, statistical disparity proves racism, then the National Basketball Association would be a racist association because 95 percent of the starting multi- multi-millionaires are black, and they make a lot of money,” he added.

“So when we hear Black Lives Matter say that America is a white supremacist nation, you know that you are listening to a stone-cold racist or a lunatic, either one,” he concluded.
