Reverse Racism in America

I heard a gospel song the other day.  It said that we had overcome.  We made it past slavery we had overcome.  We had a black president in office.  We had overcome.  Why is it that because the person that is in office happens to have a skin color different than his predecessors that should stand out as "us" overcoming?  Maybe it is because I haven't had too many run ins with racism and I wasn't raised with my parents and grandparents pointing out that I am of a different race than those around me that the fact that Obama is in office does not stir something in me.  I am glad that as a child that he had the dream to one day become president and that dream became true for him.  But doesn't pointing out that he is black continue to keep us in the dark ages?  Doesn't it continue to keep racism alive when we continue to to point out our differences.  Are we not supposed believe that we are all created equal regardless of our sex or race.
