So, you served your country just so when you watch football, you could watch people stand and sing the national anthem?  I thought most people who served our country did so to fight for peoples rights to do exactly what these players are doing.  

I guess you would rather live in a country where it is required by law to sing and praise the country all the time regardless of whats going on in it?  I think theres a country like that actually....its called North Korea.
