Not sure what your point is, but I think most people agree that a football game is the wrong time and place. I will grant you that I think the vast majority of protests are a waste of time and usually a pain in the *** for some people just trying to go about their life.
My point is every place it the wrong way to protest in this country. First the message of the protest is attacked, and the people/group doing it. Then if the protests has merit for a cause, the place where the protest takes place is always viewed as the wrong venue or place to do so. Wash, rinse, repeat.
Multi-cultural actors can't voice their concerns and hopes for a brighter common future when a VP is in their house.
Artists can't voice their concerns when people are coming to enjoy their art
Football players can't peacefully protest, so the media and pundits make it about something else completely, just to sew discontent.
This is America. You have the ability to peacefully protest in this country. Saying you can't protest somewhere, because it's 'not the right place' goes against the first amendment. I will defend 1A as strongly as 2A, 3A, 4A, etc. It all starts with 1A. And we start putting restrictions on it, then the rest of the rights will fall.
