The connection is banana -> monkeys -> black people. I don't know if you guys are just being silly with the vodka example, it has nothing to do with it.
It is definitely about his race, not about being brazilian. If it was Kaká there, this would NEVER happen.

I don't know if you guys follow football news, but I do, and that happens A LOT, not only in Russia, but with non-white people everywhere. The most famous example is Eto'o, the camaronese. Also, the supporters from Zenit had already declared that they don't want black people on the team, and their coach agreed.

I totally agree with Roberto Carlos' behaviour in this situation. It is not the first time that this happened, and it is indeed very offensive. If he would keep "being ok" with this issue (and it's not a minor one) it would never stop happening. I agree with you Hanna, these people should be banished.
