I feel a bit bad for Kaepernick in that he is badly misplaying this. As an NFL player he had both (a) a big stage and (b) access to a big income. He is giving both of those away which is going to make it harder for him to promote whatever he wants to promote.
Life marches on. The next NFL season will start in two months and when it does there will be new story after new story. Kaepernick will gradually become less relevant. Once he's out of the league the only reason to report on him will be stories like this and eventually people will say "Who cares?" People care when you're in the NFL, whether you do good or bad.
