The anthem of the revolutionary Left is a song titled “The International”. No borders means no country, they see themselves as citizens of the world.
Now remember that the Marxist rabble that rioted outside the 1968 Democratic National Convention in Chicago became the party establishment. It’s why Bill Ayers never went to prison for being a commie terrorist. It’s why Ayers was picked to reform the education system, and its why Obama started his political career in Ayers’s home.
Glad someone besides me remembers that. The Marxists of the New Left were mostly Red Diaper babies, the progeny of active Communists in the U.S. To really understand what's happened since then it's very helpful to read David Horowitz's books.
Many here don't trust him because he was a former Radical and Red Diaper Marxist himself but IMO he's done more to explain and expose that movement than any other writer I'm aware of. He rejected his past views and has shown a lot of courage exposing campus indoctrination and radicalization of university faculties.
