So, without any work samples from the author, it's impossible to say if it really was a "racial" thing, or he just wasn't very good at whatever position he was trying to get hired for. I've seen plenty of reports from people of all races being treated much the same way. I'm not saying the author wasn't discriminated against, merely that it's difficult to tell that he definitely was from an outside perspective.
