Commendable. I agree with his feelings. For me this is someone who is quietly making a statement and he is sticking up for his race. He is not using the BLM as an excuse to riot and disrespect law enforcement. He is quietly taking a personal stand and I find his reasons to be commended. As a country we have an epidemic of LEO using excessive force and killing black Americans. There are good cops & bad cops. It's scary when someone with a weapon & a badge is being excessively physically aggressive because they are always "right". It seems like cops can say outrageous things and people will automatically believe them. It is a very helpless reality. Should he stand and pledge to a country that has an admitted history of prejudice and racial hate crimes? Should he pledge because he is a NFL player and not in the ghetto? How is this different from Rosa Parks? Martin Luther King?  It doesn't mean he isn't a patriot. 
Taking a stand for what you believe in is what our country was founded on.
