I would say that there could very well be strategic advantages to being part of a "black" incubator. Peer encouragement/validation, communication, shared experiences, etc. As I understand it, culture is a big part of any startup, and a culturally-oriented incubator could attract people who mesh well together.
I am also a black programmer, yet my experience has likely been a bit different. I've found considerable social and professional benefits to working and networking with people who look like me.

This reminds me of Ellen Spertus's argument that certain women might get a better CS education from an all-girls school. The idea is an all-girl environment completely removes such impulses as "I don't want to answer this question and be 'that girl'" or any external signals that link being female with being non-technical.
