I am only posting once here and won't respond to whatever is written. I am going to ramble so be forewarned.
Actually the Star Spangled Banner was not our National Anthem until much later in our History. I don't remember when it became official, but I know it did become very popular to the Union troops during the Civil War. You know, the guys who fought and died to end slavery. My great, great, great grandfather was one of them and he was in fact (documented) very anti-slavery. He was shot in four separate battles (damn tough) and finally succumbed to it. I think honoring such folks is important, but you don't have to and that's what makes a free country great. It remains a fact that protesting social injustice, regardless of that means to the individual, will not be as well received during the Anthem as it would in other ways. Anyway...
I have been to nations such as East Germany, China, Saudi Arabia that don't give you an option, but to publicly support the state without very violent consequences. Until you are there, I guarantee you that don't really know the difference. I have had a relative fight in combat in every single war since then, including very recently. Many of them did not make it back. A LONG history as a Gold Star family. I can tell you the current President is not the only Commander in Chief in recent history to do some really insulting things to Gold Star families. The news reporting has changed to all one way or the other.
I have been in combat myself and will never mind seeing our Anthem at sporting events or the colors presented The argument made that a lot of people don't pay attention so it is less important fails to hold water with me. I see people using their phones during every act in society, to include while driving and that doesn't mean paying attention at the wheel is less important.
Of course the military recruits at sporting events. It is necessary to keep a volunteer military so there is not a draft. I like that every person in the military signed up to be there. Sporting events hits the demographic, a lot of young men and women. I think that is a lot more important than selling Pepsi or insurance.
Ultimately this entire thread is silly because in my experience nobody has ever changed their mind from postings on social media. Kind of nice that we can disagree. I have personally been in Africa where kids had their heads cut off because they disagreed with gifts of food and clothing. The male kids who were given shoes had their heads resting on the top of the shoes they received to go to school on the road leading to the village. The little girls were never found because they wanted to go to school. A little perspective of very serious oppression not that long ago. I came back from the unit I was in and became a strength coach. Iron isn't political and you can either lift it or not. One of the few things in the world without grey areas so perhaps that is what drew me to it.
However, I have never met a combat veteran (yes indulging me) who did not appreciate being thanked and didn't take the National Anthem as a symbol of pride and importance. Ultimately when you are getting shot at you become more patriotic to the flag. If you don't like, please go get a Pepsi or go on your phone. A lot of people died for that freedom.
