Alright. Firstly, racism is defined as:
The Dictionary wrote:–noun
1.
a belief or doctrine that inherent differences among the various human races determine cultural or individual achievement, usually involving the idea that one's own race is superior and has the right to rule others.
2.
a policy, system of government, etc., based upon or fostering such a doctrine; discrimination.
3.
hatred or intolerance of another race or other races.
I don't believe that, with these criteria, blacks in America are
racist, they just aren't
color blind. There is a definite difference between the two. If I say that, "I have a black friend", or "my black friend isn't doing so well", I am not being racist, but I'm not being colorblind either. Addressing someone by their race in a nonnegative or positive way isn't racism, nor is it a bad thing. Race should be addressed as a characteristic, and something commonly known and accepted such as your gender, hair color, age, etc. Just because someone refers to race as a description for something, or uses it in debate, it does NOT automatically become a racist comment.
So is Black support for Obama racist? No, it is not.
Does Black support for Obama have to do with the fact that Obama is half black himself? Yes, I believe it does.
This could be a near perfect analogy comparing the differences of nationalism and patriotism. Nationalists believe that their country is the best, couldn't be better, and that nothing is wrong with their country. This is analogous to black Americans supporting Obama, despite statistics and fact.
Patriots often get the cold shoulder for criticizing their country, trying to extrapolate on their countries faults, and disagreeing with policies. This would be analogous to a little over 9%, I imagine, of the black Americans who don't approve of President Obama's economic policies.
