Muhammad Ali was a polarizing athlete that provoked an intense negative reaction several times. 1st was his conversion to Islam, then his name change (Cassius Clay was his "slave name"), and then his refusal to submit to the military draft. And for those too young to know, the white establishment went berserk. Ali paid a huge price, merely for exercising his rights.

Blacks in the limelight due to celebrity, that choose to shine light on causes that matter to them are not "martyrs." They are people that have unique opportunity to apply their celebrity status to a greater purpose, other than self centered gratification. Kap deserves respect for turning attention to police mistreatment of black people. Bigotry and racism are still with us today.
