No but its about identifying progress which we have made. Sadly, justice doesn't happen overnight but the forcing of it often times hurts that progress. I would like to believe, easy for me a white man to say, that MLK would be thrilled at the opportunity afforded to black people in this country.
But that's not the point. Just because there has been progress, it doesn't mean Colin Kaepernick shouldn't be trying to make more progress. I'm not sure what you mean by the forcing of justice. If you mean we shouldn't have things like Affirmative Action or whatever, I guess there's at least a substantive debate to be had, but the point at issue is people calling out Kaepernick for protesting actual injustice then thinking they have the right to spout the message of Dr. King.
