As the NFL season begins, the controversy around former San Francisco 49ers quarterback Colin Kaepernick continues to grow. Ever since he took a knee (instead of a seat) during the national anthem last year, the debate around Kaepernick has careened from arguments about institutionalized racism and free speech to respect for the military.

To his supporters, Kaepernick is a defiant champion who continues to inspire other NFL players to take a seat or raise a fist in support of racial justice. To his detractors, Kaepernick’s refusal “to show pride in a flag for a country that oppresses black people and people of color” represents an unforgivable sin — a betrayal of the military members who ostensibly sacrifice for liberty and freedom.

Over the past few weeks, however, Kaepernick’s fight has sharpened into a protest over his job situation. As teams continue to sign lesser players to free-agent deals, many believe the NFL is sending a message by not hiring the outspoken QB.
