If the black students knew the deceased and knew he would appreciate being honored with a confederate flag display, then in a normal society, THEY would have dressed up in confederate gear for him.
But we have a society which demands that blacks are brainwashed from birth to adopt a victimhood role, and never to think or act apart from that role.
Too many blacks have been conditioned to simply be spectators as the world passes them by; in the past it was a “white” world, and now they are spectators as foreigners come in (imported to replace the disappearing white population) and leave them in the dust.
