Besides the misquote, people of color, and especially black folk, are regularly told to "calm down" to "get the message across better." But what happens when an athlete like Colin Kaepernick calmly and quietly takes a knee in protest? The dialogue explodes around his being disrespectful and not about the issues he is actually protesting.

Besides which, responding to someone's call for help on life and death issues with "calm down" is patronizing to the point of inhumanity.
