Answering my own question - from wiki:
------------------
Maulana Karenga of the US Organization created Kwanzaa in 1966 as the first specifically African American holiday .[2] Karenga said his goal was to "give Blacks an alternative to the existing holiday and give Blacks an opportunity to celebrate themselves and history, rather than simply imitate the practice of the dominant society."[3] The name Kwanzaa derives from the Swahili phrase matunda ya kwanza, meaning first fruits of the harvest.[4] The choice of Swahili, an East African language, reflects its status as a symbol of Pan-Africanism, especially in the 1960s.
Kwanzaa is a celebration that has its roots in the black nationalist movement of the 1960s, and was established as a means to help African Americans reconnect with their African cultural and historical heritage by uniting in meditation and study of African traditions and Nguzu Saba, the "seven principles of African Heritage" which Karenga said "is a communitarian African philosophy".
During the early years of Kwanzaa, Karenga said that it was meant to be an alternative to Christmas, that Jesus was psychotic, and that Christianity was a white religion that black people should shun.[5] However, as Kwanzaa gained mainstream adherents, Karenga altered his position so that practicing Christians would not be alienated, then stating in the 1997 Kwanzaa: A Celebration of Family, Community, and Culture, "Kwanzaa was not created to give people an alternative to their own religion or religious holiday."

Reading the history based in angry black militarism, I hope Kwanzaa does die off. It reminds me of Muhammad Ali becoming Muslim based on that he wasn't going to follow 'a white blond blue-eyed God'. Not a very good reason to become something else in my opinion. His religious views may have grown since that time. I happened to have watched the movie Ali in the last few weeks and found that portion of his story disturbing. Reading the history of Kwanzaa leaves a similar feeling. It seems more anti-something than celebrating something.
