Blacks push for inclusion when 'they're' being included but fall back to 'tribal mode' when dealing with other minority groups. Blacks (unlike white liberal elites) seldom push for 'rights or advantages' for Native Americans or Hispanics or any other minority groups.
The End Result?
Non-black minority voters - Hispanics, Native Americans, Asians, Native Hawaiians and other Pacific Islanders etc will gravitate toward the Republican Party.
Or, blacks break apart and form their own third party.
Either way works out well for our side.
