In my youth, the differences between the Soviet Union and the United States were made abundantly clear to us. We had the freedoms enumerated in the Bill of Rights, and they didn't. Teens at drive-thru fast food restaurants were iconic of American freedom.
The freedom to recreate our culture through music, food, mobility.
Our fathers fought despotism in World War II and Korea and told us of the communist menace, always juxtaposed with the freedoms for which they fought.
