No doubt, because it keeps him in the public eye.
I don't know the guy so can't opine on how genuine he is, but I strongly suspect he wouldn't have put up with all that crap if he didn't really believe in his protest. And regardless, he didn't do anything wrong, kneeling is his right. Now I couldn't care less what he does during the National Anthem, but obviously some people do, and those people feel just as genuinely in their opinions as Kap does in his. And therein lies the real issue with the Alphadog PC-rant above.
He distills everything down into the narrow view that anyone who doesn't genuflect at Kap's feet is just wrong and probably a racist. And for some reason I really set him off with the mention of Kap's effort to rehabilitate his public image. It seems rather naive to think that regardless of what other motivations he has, Kap wouldn't be aware of the potential positive impact on his reputation at a time when he's looking to stay in the NFL. Apparently that's because Alpha views the act of marketing oneself as some kind of dodge for shady people, which shows a odd lack of understand of the imagine-driven world around him.
