You added the word "political." But, of course standing for the National Anthem is a statement. Otherwise, what's the point? And, why would anyone care when someone didn't? If kneeling is a statement, then so is standing. Unless, of course, we, or the players are forced to stand. Then, it becomes meaningless.
Also, if posters on this board needed excuses to voice their opinions, you'd better have a whole lot of them!
