I agree. Believe in something and while doing it, undertake the process for change available to every other citizen in your country rather than grand standing at the sidelines of a sports venue.  Western democracies are endowed with the right of speech freedom. This right empowers citizens irrespective of race, sex, or religious affiliation to express themselves in the public domain. What is the public domain? Well, you can write a letter. You can recite your beliefs on a street corner. You can visit a government official. You can attend a political rally.  You can start a political party. You can espouse your beliefs in conversation. You can light up the twitter sphere with one liners. You can form an organization as a form of lobby. As you can see, the opportunity to freely express oneself has many outlets.

Colin Kaepernick had chosen a method of expression convenient to him in an apolitical domain – the football arena in a football uniform employed by a football franchise in the spotlight broadcast around North America via television. He chose an outlet reserved for an occasion other than politics and it was his right. The interesting thing about his behaviour is that his employer has the right to sanction him accordingly for behaviour not in accordance with his duty.  His behaviour will obviously impact the perceptions of other potential employers.  Some citizens loyal to his cause may empathize with his plight and even lavish him with praise of courage. However; it would be misplaced. I view Colin Kaepernick as a career martyr deserving of his plight. I consider him lazy for not pursuing the outlets of expression available to him with the same vigour in parallel to the apparent passion he brings to a cause.  

As for Nike’s endorsement of him, I’ve been avoiding Nike in stores for decades.
