I know it’s not going to happen, but the United Nations should declare May 1st “International Victims of Communism Day”. To this end, allow me to share my colleague and friend Ilya Somin’s original May Day Proposal from 2007: see here or here. Below is an excerpt, which I have lightly edited for clarity and style (all links are from the original):

Today is May 1st or “May Day“, which began as a holiday for socialists and labor union activists, not just communists. But over time, the date was taken over by the Soviet Union and other communist regimes and used as a propaganda tool to prop up their regimes. I suggest that we instead use this day to commemorate those regimes’ millions of victims. The authoritative Black Book of Communism estimates the total at 80 to 100 million dead, greater than that caused by all other twentieth century tyrannies combined. We appropriately have a Holocaust Memorial Day. It is equally appropriate to commemorate the victims of the twentieth century’s other great totalitarian tyranny, and May Day is the most fitting day to do so. I therefore suggest that May Day be turned into Victims of Communism Day.
