I think we were told the line theory so that we would believe the middle is the place to be. That is, agreeing to accept a little socialism is good. Now I like to think of it as the right is freedom and the left is subjugation, no matter what name it goes by. Fascism and Communism are BOTH Progressive and thereby bad.
I agree. His using the circle was probably because fascism and communism were arbitrarily placed at opposite ends of a spectrum. On a linear “freedom/liberty” scale, communism (no private ownership) and fascism (private ownership w/ government telling the owner exactly what to do with it) are right next to each other over at the “not-free” end.
