The fans were protesting long before Our President Donald Trump ever made a single comment.  Personally if our President didn't stand up for the Flag, and Anthem he wouldn't be a patriot.  Our last guy would be taking a knee in the Oval Office, a complete moron.  I believe they need to rechallenge the burning of our flag with the Supreme Court, get it protected.  It is a national treasure just as much as our constitution and the bill of rights.  Burning a flag is arisen really, that flag could catch something else on fire and spread possibly killing someone.  It's not freedom of speech, that flag isn't speaking, it's the traitors loud pie hole that's speaking.  The flag is an inanimate object, in battle the rally point.  It's the only thing a loved one gets to see and hold when a great American fighter is brought home from the battlefield, with it draped over their coffin.  Tell a Gold Star family that that flag means nothing.  There's a million other was to address your grievance.
