Yeah, and ask them how many people died in the communist revolution in Russia.
"Stalin who? Lenin? Oh yeah, that Beatle guy."
I went through several Political Science and Philosophy classes in college, and NOT ONCE did a professor mention the violence, famine, squalor and disease that has accompanied the communist revolutions.
I recently used a couple of expressions that left the boss's 16 year old privately educated son going "Huh?" Iron Curtain and Cold War. You could almost watch the glazed look form in his eyes. Sad. One day his generation will run the world. Who was it who said "he who ignores history is doomed to repeat it"?
