Oh great, the FBI wishing you a merry holiday for a bogus holiday created by a felon.

From the Urban dictionary:
kwanzaa
A holiday developed by a Dr. Maulana "Ron" Karenga, a black militant, Marxist, and convicted felon.
Just five years after this, he was convicted of torturing two black women to death.

Observed from December 26 to January 1, Kwanzaa is based on a mixture of East African harvest rituals, called "first fruits" by Karenga and 1960's radicalism. This is in spite of the fact most slaves came from West Africa.

Viewed as an "alternative" to Christmas, it, nonetheless, is based on race, and not in faith.

Then there's this:
