That was nice of you, but you aren't entirely wrong in that statement. There are people out there who know just how great the man is in this sport, but they would never admit it, and they would never admit why they hate him. Some white people fervently believe that a white driver should always be the best, especially in a sport where no other black man has been involved. I'm not saying this about all white people of course, but as I said there are people who feel this way.
The more that Lewis achieves in this sport, the more bitter "they" become because it isn't a white driver, or the driver that they prefer it to be. I live in the states where a black baseball player named Hank Aaron broke Babe Ruth's longstanding homerun record. Some white people believed that he should not hold such a record because of his color, and yes he received tons of death threats which involved both him and his children alike.
Now let's consider Europe where black soccer players are constantly humiliated for their skin color while doing their jobs, ie bananas thrown on field, monkey sounds and the like. My point to you is while you should not point fingers directly on this forum, we both know that the sh*t exists in the world in which we live. Some people will say that they don't like him for a specific reason, but there are other reasons you can bet. Again, I am not saying this about anyone on these forums, but..... ahem ahem. They know who they are indeed.
