Hey lets ALL celebrate Kwanzaa! Why should black folks get all the fun! We need a Kwanzaa Klaus! Black guy in a colorful dashiki. Lets hijack the holiday and make it a Fun time for all! Lets make it the joke it should be.
How about turning it into a drinking holiday.
Did a saint convert your island to Christianity? We'll drink!
Did you win a single battle against the French (but lose the war anyway)? We'll drink!
Do you celebrate huge mugs of beer in Munich? We'll drink!
So why shouldn't a made up holiday of a harvest festival during a time when nothing is being harvested, using terms from a language from the wrong side of the continent invented by a torturing thug be turned into a week of drunkenness?
