why are so many racist question in Yahoo?

Recently I red some question about if there are some white people in P.R. and one guy said: he never seeing a white people in Puerto Rico. He must be an African. These people should be reported. For the one who said that he never seeing a white from Puerto Rico must be an ignorant who don't have any education. I don't care if there dark or white we are the same. I think some people need more education and seach Google before they answer. I'm tire of these already. It seem to me that this people should be reported. This is a place to learn and help people but I don't see it that way any more. This type of question and people who put other people down for the nationality should be reported. They are people white and dark everywhere.
