Since Juneteenth has been passed and now seen as a federal holiday for blacks....the question arises....what about the other folks?
Hispanics? Cinco de Maya.
Indians? Gandhi Jayanti (2 Oct).
Indians (Natives)? 4th Friday of every October, American Indian Day.
Irish? 17 March. St Patricks Day.
British? 26 December, Boxing Day.
The odds that at least three additional holidays will be 'forced' over the next five years? I'd give it better than 30-percent odds.
