This is an interesting look at the original writings of Dr. Maulana Karenga, the creator of Kwanzaa, by Carlotta Morrow. Ms. Morrow set out to discover what she could about Dr. Karenga and his agenda when her sister renounced Christianity as a white-man's religion after joining Dr. Karenga's Black activist group called the US Organization. Her research led to the discovery of a much more militant attitude than she expected, and the discovery of many contradictions between Dr. Karenga's original hard-line writings and his current, more inclusive writings. In his own words, Dr. Karenga shows an anti-Christian attitude by renouncing the Resurrection, heaven, and hell as "Christian myths", and commenting that "[w]hen messenger Muhammad taught that we are Gods and can make history and remake the world in our own image and interests, he set a good example." Christians will find this site enlightening.
Yep. The only blacks I've ever seen celebrating Kwaanza have been on the human interest part of the TV news.
Being black myself, I don't know a single middle or upper class black person who celebrates it. From the looks of the folks shown on TV, they appear to be of the lower classes.
