Ok, before I post my answer, don't all freak out and wack me over the head with a mop.

Not a major follower of F1 but come on, Hamilton is the favourite given the fact that he is a Brit and the F1 is Brit owned. No racism just favouritism and based on that they have to penalize Hamiliton to 'demonstrate" fairness. Just listen to the comentators...its all about hamilton, hamilton, hamilton....

Good on him but to answer the question, racism is not "practiced" in F1.
