Hardly, I am another black programmer and I've had the fortune of working with other black programmers, whites, Asians, Polynesians, Hispanics and more. He is not the exception. Racism is just not a thing in the high-tech industry. If there are any negative vibes towards a person because of their background, it's only ever because of their "foreign-ness"; if for example they might have an accent. Even this is quickly brushed off wherever I've worked. High-tech doesn't care what color your skin is or where you grew up. The best hackers I've been honored to share a repository with have been from countries I've never been to in the former USSR and South America, all of varying ethnicities.
This is a false issue that is being propagated by someone to garner attention to their accelerator. This whole idea of a race-based fund for high-tech is repulsive to me. If there are black entrepreneurs out there in high-tech, what is wrong with applying through YCombinator and other established incubator programs if they need the coaching and funding to go to market? It's insulting to think that blacks cannot compete for whatever reason in a normal fund and have to go make their own one and then blame it on perceived "racism". Big cop-out card there.
