Do you think it may partially be rooted in the difference between actually earning something or having it handed to you, unearned, because of skin color?
Another poster mentioned people like Colonel West and Dr. Benjamin Carson. I think people like them, like Thomas Sowell and Walter E. Williams communicate the self confidence that comes from knowing they are on solid ground - they know their subject matter and know they have earned their standing in the world.
On the other side of the coin are people like Eric Holder, Barack and Michelle Obama who know they have not earned the standing or awards that have accrued to them. People like that tend to come across as overly race sensative, thin skinned, defensive and more than a little too aggressive at every imaginary slight.
How much significance can Obama's Nobel Peace Prize really hold for him or anyone else who knows it was just another Affirmative Action token?
Even Obama knows that his award does not carry the same value or meaning as those of more worthy Nobel Laureates like Lech Walesa, Mother Teresa, Andrei Sakharov or Albert Schweitzer.
Possibly in some part. But I think it also has to do with hatred that has been instilled in them throughout their lives and also with power. As long as they can make white people feel guilty, they have power over them. Sowell, Williams, West, Carson et al do not desire and actually consider it quite ludicrous to want and to hold that kind of power.
