Kaepernick is an opportunistic attention-seeker and was recently voted "Most Hated" player in the NFL. Sales of his jerseys are spiking because people are buying them to burn them. He only did this because there was talk of trading/cutting him, so to protect his own ass he phonied up this self-righteous "cause," to undercut the situation and make it look like a PR nightmare for the team if they did cut him.
