First of all, you have no idea what Kaepernick is doing with his money or time; you have no idea what he supports and what he doesn't so maybe shove the fake outrage in your back pocket.
I'm not willing to accept that there will always be inequality and that's just how it is, nor should you. The viewpoint you expressed in that second paragraph is the textbook definition of white privilege. I'm not willing to accept that I am less likely to get equal medical treatment if I get sick or injured, I'm not willing to accept that my daughters are four times more likely than their classmates to get kicked out of school, I'm not willing to accept that it would be harder for me to rent property than someone with less money and melanin than I, I'm not willing to accept that if my wife and I die in a car wreck on the way to Kansas City tomorrow that my daughters are twice as likely to stay in the foster care system and get separated. Should I go on? Its easy for you to brush this stuff off because it isn't your reality, its mine, I can't just forget about it.
