I disagree that racial discrimination has gotten better. The only change is that it has been reversed. Employers are scared to reprimand or terminate employees of a "minority" race for fear of a suit or other negative repercussions, however there is no hesitation to implement this recourse on a "majority" because it is no threat.
One other comment: I thought we were all Americans, so doesn't the label African-American perpetuate the segregation of people?
I do not go around touting a self-applied title of French-Irish-American. Everyone's blood runs the same color and that's where all of this should end.
