When you get to be my age you have grown tired of butthurt. Everybody is always butthurt over others exercising their rights or asking for equal rights and treatment under the law. So, let us get this clear from the start, demanding people stand for the anthem is unconstitutional, according to the Supreme Court. It does not apply only to public school children.
I honestly do not care who you side with on NFL players kneeling, but the law is clear. I am sure lawyers could argue it until they are blue in the face, but we can not be forced to endorse nationalism (there is a difference in nationalism and patriotism) or subscribe to the "my country right or wrong" ideology. Once we go down that path everyone will get hurt, and butthurt.
The NFL made the decision to keep the debate going, and the same people who praised the sanctity of marriage woman with a history of divorce for not doing her job by denying a marriage license to a same sex couple will no doubt be unable to see their hypocrisy in action as they sit on their butts screaming at black players kneeling during the anthem. We are in for a long Fall and Winter with an above average chance for butthurt.
