So? What does that have to do with anything.

You started by MLK quote and ended by complaining about divisiveness. The speech that quote is from is call for radical action that won't stop. It was not call for peace.

He was someone who pushed for what he wanted in multiple areas. Very outspoken, openly talking about race and powerty.

MLK wanted unity but because some people did not support such things MLK was considered divisive. He would almost certainly be against pushes like this and that was what I was trying to convey. He believed race was not an important attribute of a person. We now have people who think it is one of the most important thing.
