I think the point is that the name is disadvantageous because it makes people think that he's black, and black people cannot stop being black. In other words, if you're actually black, then you can't escape racism just by changing your name.
I'm not sure what you mean by "political tastes". I'd have thought pretty much everyone was opposed to e.g. refusing to rent an apartment to someone because of their name, or because you think that they're black.
