All people who proudly wave the Soviet flag are either oblivious to history or in denial about history. Life under the Soviet system was total hell. Approximately as many people died because of Soviet control as died due to the evil Nazi regime.
The beautiful thing about America is that people are free to wave any flag that they want and believe in any cause they want. It’s just sad that too many (but not all) Americans have not learned this simple lesson from the past: Freedom will never come from greater state control.
