You are right that there is no real difference between the Far Left and the Far Right in their collectivist and totalitarian outlook.

The big difference is the general acceptance given to the far Left in this country. The "mainstreaming of Marxism" as it were. Anyone can stand up and say they are a socialist, (or a "progressive," as the latest euphemism for "Marxist" goes.) Movie stars, academics, media people, authors, you name it. They wear their leftism as a badge of pride. If any one of them stood up and said they were a fascist, it would mean their immediate expulsion from society.

Count the number of active Klansmen teaching kids in American colleges today. Now count the number of active Marxists doing the same thing. See the problem?

However, it is encouraging to see the number of thoughtful liberals finally condemning the Leftist looney fringe. Took them long enough.
