Here's what another website says: "David Joel Horowitz (born January 10, 1939) is an American neoconservative writer, and activist. The son of two life-long members of the Communist Party and once a prominent supporter of Marxism as well as a member of the New Left in the 1960s, Horowitz later rejected Leftism and is now a prominent advocate for right-wing causes. He is a founder of the David Horowitz Freedom Center (formerly the Center for the Study of Popular Culture), and has served as president of that organization for many years. He is the editor of the conservative website FrontPage Magazine, and his writings can also be read on prominent news sites and publications, including the conservative magazine NewsMax.1
He founded the activist group Students for Academic Freedom and is affiliated with Campus Watch. He occasionally appears on Fox News Channel."
