Formerly-marketable San Francisco 49ers quarterback, Colin Kaepernick, chose not to stand during the national anthem prior to an NFL preseason game. It was a gesture to illuminate the racial inequalities in America.
The 49ers delivered a very measured response to Kaepernick's gesture. The NFL's official statement was also quite plain, "players are encouraged, but not required, to stand during the national anthem."
And that was the last anyone heard of—oh, right, fragile, bloated football racists can't interpret any act of defiance to Americana as anything but an attack on dad, Fido, democracy, and their ninth-grade schooling on FREEDOM.
