Remember the VICTIMS of Communism on May Day!

Today, May 1, is -- as we all have heard repeatedly -- International Workers' Day. It's instructive -- if not very informative -- to look at al Jazeera's take on it.

Each year, people across the globe take to the streets to commemorate International Workers' Day, or May Day.

In dozens of countries, May Day is an official holiday, and for labour rights campaigners it is particularly important.

In the United States, it is symbolic of past labour struggles against a host of workers' rights violations, including lengthy work days and weeks, poor conditions and child labour.

Of course, starting in the '20s, and eventually formalized in the '50s, the United States made it Loyalty Day. Also Law Day. We've already seen how Loyalty Day has suddenly become a Big Deal this year, so I won't repeat myself. But May 1 is also suggested as a commemorative day for another, much darker, reason. Ilya Somin has been campaigning for years to have May 1 declared Victims of Communism Day.
