Look, an employer can fine employees for almost anything they want. I have no problem with that if you know that as an employee going in.
I do have a problem with any employee or school or anyone telling anyone else that they are obligated to stand for a pledge, an oath, a fucking song that proves some dumbfuckery notion of patriotism.
Patriotic tests are un-Constitutional.
Any veteran who tells you otherwise has forgotten his/her oath.
You want to stand for the National Anthem and face the flag, I will fight anyone who tries to stop you.
You want to peacefully protest during the same National Anthem, I will fight anyone who tries to stop you.
Seriously though, I am thinking about ditching the entire NFL after this.
Fuck Roger Goodell and his dumbfuck minions.
