That post-racial society has existed already for years.  It isn't a new development.  Spent a lot of time in Cabbagetown years ago.  All races lived amicably in the building I was in.  I think this constant push on race and racially charged identity politics is actually harming race relations.  Equality is equality.  Sending a specific group to the back of the room does nothing to further equality.  Constantly taking the wrongs of the past and putting them back into today's context achieves nothing other then some smug, arrogant, self righteous and selfish feelings of self-affirmation for the one initiating the act, in this case the singer.
