President Obama is both black and white by genetics and he's openly acknowledged that.   

 Have you ever been drawn with a bone in your nose? Have you received thousands of death threats based on  race?   

You demean a man because you can't understand his experience.   You can not walk around Eugene in a black skin and see the reaction.   You simply do not know the President as a man, nor do you care about him as a person.     

Do you seriously believe that if a person points out white prejudice that it makes them biased?     

Please note that I am not denying black racial bias against white.   But you have only mentioned one side of the story.   The President has every right to speak his mind and that includes the prejudice that he has personally experienced as well as racial animosity that still exist in this country.   I believe that the President has been almost superhuman in the way he has endured the false claims against him based on his race - from whites and blacks
