Well, there were rumors of Spanish GP being cancelled and withdrawn from the F1 callendar if the racism continued. But it was just left at that
Also, Hamilton has stated before that yes he does dislike it and it makes him feel uncomfortable ect. But when he is in his car and out there racing, it doesnt bother him a bit.
However, this doesnt mean the Spanish can throw stuff and shout "n..." at him....
For God's sake he isnt even that black, it looks like a really deep sun tan to be honest. :/ Dont see how people can dislike a person just because he is different skin colour.
