According to the Official Kwanzaa Web Site, Kwanzaa isn’t just an artificial holiday invented by an American in order to have a “Black holiday” that explicitly excludes anyone of any other ethnicity.
As an African American and Pan-African holiday celebrated by millions throughout the world African community, Kwanzaa brings a cultural message which speaks to the best of what it means to be African and human in the fullest sense.
Of course, they neglect to mention that nobody in Africa celebrates Kwanzaa. Why? Because they have enough traditional holidays as it is, they didn’t need to invent one that sounded like a traditional holiday but isn’t.
