However, when he says that he is almost the only non white face in an industry of many thousands of people, I can sort of see where he is coming from.
Historically, race fans have tended to come from the white community. Hamilton showed that, if you have talent, then it doesn't matter what colour you are. So, if a black driver (like Bubba Wallace in Nascar) shows talent, then colour is no block to reaching the top tier. HOWEVER, the fact that there are few blacks, relatively, in F1 and racing in general, does not reflect racism, merely the fact that the sport does not have a widespread black fan base such as football, basketball, boxing, athletics etc. The problem is that Hamilton is trying to equate a perceived lack of black participation in motor sports as discriminatory – which it clearly isn't.
