In 1962 I joined the Air Force and went to San Antonio for boot camp.  I learned a few things during that time that are still relevant.  The instructors told me I was welcome to believe anything I wanted, and to say anything I wanted so long as I was not in uniform.  Once I put on the uniform I gave up those rights because in uniform I represented the United States of America and anything I said or any action I took would be attributed to the United States.  Those are the rules that prevent military members from campaigning in uniform for any political party, candidate or cause. 

The point here, is you must consider how your actions will be perceived.  If you drive like an idiot in a Mercedes, the perception is all Mercedes drivers are idiots.   If you have a religious bumper sticker on the back of your car and you just cut someone off, all members of that religion are assholes. 

The NFL has sullied its reputation by not taking decisive action to stop the public disrespect to the flag of our country which can only be construed as disrespect to those who have fought to defend her.  I have waited to see them take action to stop this insult and although the people in charge of the teams and the league have not condoned this action, they have not stopped it either.  When you put on the uniform of a professional sports team, your actions reflect on that team.  Sporting events are supposed to be entertainment.  If a sport fails to separate itself from politics it is no longer entertainment.  Regretfully, I will no longer be supporting the NFL in any way, including watching the games on television.  

Last week, NASCAR decided to jump on the racial bandwagon in several ways including an insulting rendition of the National Anthem by someone who had apparently never heard it.  Then they dedicated race cars to the obviously racist BLM organization.  I've watched their races since the fifties and attended some of them, notably in Darlington and Daytona.  I won't be watching any more. 

If you agree with the stance of these organizations then by all means support them.  If not, consider voting with your pocketbook.  That is the American way.
