He's well within his rights to do what he's doing, because free speech. Free speech only means you can't be prosecuted for voicing your opinion, though.

How the fuck am I supposed to concentrate on football if all anybody is asking me about is my quarterback's "protest". His pretty rapid decline in performance was already a shitshow, and this is just piling on to that.
