Vicarious repentance

Articles like these on Ref21 therefore really irritate me. Such smacks to me of assuaging white guilt rather than solving racism. Speaking of which, how often must a group of people apologize before everyone can move on? As for dealing with racism explicit or implicit, why the continual dichotomy as if only whites and African-Americans are present? What about the various Asian groups? Or is Sean Lucas only interested in affirmative action just to *prove* he is not racist (and so practice reverse racism in the process)?
