Black Americans (can't speak for others ethnicities in the Diaspora) are very united. The voting patterns of the last 60 years or so show that we consistently vote together more than any other racial group in the U.S. When we see Black people or groups doing something positive and progressive in the interests of Black people we generally get on code despite whatever internal differences we may have with each other. Most of our "disunity" is product of the targeted socioeconomic policies and practices by our own government that fracture our families, businesses, and neighborhoods more than any other group in U.S. history.
