Rightwing radicals or Maoist revolutionaries?
Though they're often featured guests on cable news, radical rightwingers have become so virulent and un-American, they're virtually indistinguishable from Cultural Revolution Communists. See if you can distinguish: "[Their leader] actively urged young people to confront, denounce, and even punish their teachers and other authority figures in their lives." vs. "[His] organization has published ads in campus newspapers calling on students to report professors who try to 'impose their political opinions' in the classroom." There's more, much more. (Whiskey Bar)
