May Day
The May Day association with labor is all American, and just as controversial as everything of any consequence in history. The day is tied to a strike for the eight-hour day and the so-called “Haymarket Riot” of 1886. When it comes to “riots” and the Chicago police are involved, you are not going to find a single truth.
The dynamic duo that mucked up the Pledge of Allegiance, Dwight Eisenhower and his Republican Congress, made May 1st both Law Day and Loyalty Day so those Commie working people wouldn’t get any ideas about having rights.
In Europe it is also celebrated as the first day of summer with maypoles and bonfires.
