I've served, so I guess I now have the right to an opinion (as does everyone who has not served, by the way.) One, it is basic business practices 101 that you don't give your customers the finger. Yes, you may "have the right" to do that, but you are the one who eventually gets screwed, especially since professional sports is a luxury product, i.e. consumers don't "need it" like they do food or transportation. Two, people in the United States do not wish to be subjected to a partisan political rant every time they make an economic transaction, which is why places like Starbucks don't allow their employees to preach to you as part of your coffee purchase. And lastly, disrespecting the flag and anthem is disrespecting the whole idea of the United States, showing disdain for the very concept of freedom and liberty that makes the protest possible.  But, do whatever you like, I've quit watching.
