So NFL players want to kneel during the national anthem? Good for them, agree or disagree these guys, just like you or I are entirely within their right to do whatever the fuck they want.
Think it's disrespectful to the people who fought and died for our freedoms? Think again, it's because our freedom was fought for and died over that we are free to be the ass holes we want to be today, it's not a right given to us by the government so much as it is something we are all born with; the right to be obstinate stupid ass holes.
Get off your high horse and worry about yourself.
