Took a knee or picked their nose or something.
If someone in the military took a knee while in uniform and in formation, they would be taken to CO's mast. But, you can't compare the military to what civilians are allowed to do because you lose about half of your rights when you join.
Shoot...............we were forbidden from wearing our uniforms to a political rally that supported a particular candidate, because that could be interpreted by some as my particular service being in support of that candidate.
And, a quick question for you conservatives..................Trump is the president, meaning he's the leader of the government. The NFL is a private owned business. Trump told the NFL that they needed to fire anyone who took a knee during the anthem.
I thought conservatives were against the government telling private businesses what they can or can't do.
