how to fix this article
In some kinds of academic discourse it's considered incorrect to use the term "racism" to describe what are essentially racist actions by an oppressed minority. I understand, and even, in certain contexts agree with this. However, I don't see anything wrong with calling Black supremacy racist when were talking about the kind of Black supremacy that explicitly says that non-black people are inferior.

The problem I have with this article and the article on Black Power is that they both, at times, conflate the legitimate, if reactionary, anti-racist, black empowerment movements with cultish and fringe ideas and groups that have little or no currency in the greater US black community.

A comparison would be if you equated all people who are pro-life with skin heads. I bet there are a lot of pro-life skin heads, and both groups have a lot of white people in them but they don't really have anything to do with each other. (!)

In order to fix this article and the article on black power we need to realize that there are racist fringe groups, and describe them, and their history and motivation fairly.

I have a few questions: 

Is every group listed here a "self described" black supremacy group? Or are some of these groups concerned about "black power" (there is a difference!)

Do we represent the history of these groups and the racial climate they grew out of fairly?
