I believe you can question Kaepernick's motives all you want. This is as much your right as it is Kaep's to voice his opinion. However, he's neither wrong in message nor actions. Kaep, in reference to Dilfer's ridiculous commentary, for example, is becoming a (the) spokesperson for a group of people who can't/don't/won't speak for themselves. All the evidence one would need would be the uncomfortability shown by massive swaths of white America as he continues to make his feelings known and refuses to back down from his growing position of power. And that's where it really gets tricky. His power grows and the uneducated, ignorant and prejudiced masses writhe and stumble through their own sordid commentary in bars and on message boards across America and beyond.
Plainly, if you don't understand just how American it is that Kaepernick is using his position of relative power and absolute exposure to discuss injustices and inequalities and further the discussion to a national commentary that has long left out those without the ways and means to speak for themselves, you're doing it wrong. And the sad part is that you probably know you are. Are the socks cheap shots? Maybe. Is the afro a bit much? I suppose it could be. But it's working. And isn't that the point?
