Personally, I think the author is way off base here. He is either confused about the meanings of Patriotism versus politics, or he is trying to confuse his readers. The national anthem is about patriotism, love of country. Politics is about governance.  If you have an issue with how we are governed, don't attack symbols of patriotism, that's like throwing gasoline on the fire. You're going to anger those who are patriotic, and end up doing more harm than good. (which is exactly what happened) Address the problem in the proper arena,  if you want positive change, well, do something positive.
