I'm seeing a wild parallel in history happening. Even before MLK came on the scene. Blacks were marching to be treating equally. They were fighting similar "union" thugs in the south. Thugs who would beat them for their showing up at places, or opening their mouths to disagree with the "established" leadership.
It's here and now happening again. Same scenario -- and what were these protestors for? An initiative to ban government institutional use and practice of racism.
