I agree that this should go more in the political area of the forum, but since it's here.
I can respect Kapernick for kneeling for what he believes in. I still fully disagree with during the anthem is the proper time for it, as right after the anthem would be more appropriate. OR heck, after each quarter even.
Also, I fully believe Kapernick has deeper, more extreme views which he seemingly hinted at early on, but then clammed up, and just went with the less extreme social justice stance. When, I think the original sitting was a bit different stance than the current one being promoted.
As for Kapernick vs Pat Tillman, there is no comparison IMO, as Tillman willing left the NFL in his prime, knowing there was zero chance for him to do both at the same time, including leaving his family, and his wife to risk his life against bullets. While Kapernick was willing ruffled feathers, but he hoped and thought he could do that AND continue to play at the same exact time, risking being blackballed.
Those aren't the same thing to me. Though, I can respect both actions (even if I'm not sure I agree with the reasons behind said actions).
