To be honest, I couldn't care less what these pampered little knuckle draggers do. They can kneel, sit, even lay down on the field for all I care. In order for me to care, I'd have to respect these people, what they do and who they are. I don't. They make their living playing a game for crying out loud!
But I do agree with the President. You work for a company, you represent your employer. You are the face of your employer and you are expected to reflect their values in the best possible light. These overpaid idiots are not doing that. Anyone else, in any other profession, would be fired if they pissed off their employer's customers, hurt their revenue and threatened their profitability.
