Anyone with a basic understanding of this country's founding principles will defend an individual's right to hold any opinion they choose, but the minute that opinion goes into the workplace and affects the branding of an employer, that employer has every right to control the expression of that opinion.

Trump is simply saying to the NFL - if you know what's good for your firm, protect your brand because these few ingrates are using their personal feelings to destroy it.

I challenge everyone who supports their behavior on the field before a game to go to work on Monday and do something similar (i.e. on the front steps of your employer's main entrance next to their sign). I'll bet you don't go back to work on Tuesday.
