When all this sitting/knelling during the National Anthem began I was as upset as most of you are!
Then I had an epiphany (I looked that up), "Every-time they do that, no matter who it is, they are declaring that America is the greatest country on earth and they are honoring all who stood the wall defending their right to do that act!" So when you see athletes or whomever do that, they are broadcasting to the rest of the world that they live in the greatest country there was, is, and will be, because if they did that in Russia, Syria, North Korea, China, or anywhere the government tells them what to think or do, they would be killed on the spot, and here we argue whether it's right or wrong they have the constitutional freedom to express themselves peacefully!
