Ironically, one striker yelled at a black substitute, “Rosa Parks would be ashamed!” (See the video here.) Perhaps, but her shame probably would have been aimed at the obnoxious striker.

I doubt it. Rosa Parks was an agitator - AKA "community organizer" (ring any bells?)

You obviously are ignorant of the world in which Rosa Parks lived. She put her life on the line. So did Martin King. Obama, by contrast, risked nothing, did not even stay to devote himself to uplifting the lives of “his”people. Instead he has grasped the brass ring of power, lifting himself but not them. All he gives the black community is his reflected glory.
