Every vet I know stopped watching football.
I didn't and neither did a single one of my friends.
Until it's not a part of sporting events across the country they should stand. My view on the anthem and the flag is that it is meant to be about the sacrifices people made to build this country, from the Revolutionary war to the Civil War and on. I stand to honor those that went before. I don't stand because I love the President, or because I think everything is perfect.
I stand too, I hope that everyone stands, I hope that everyone feels they have a reason to stand and be proud. Some don't feel they do have that reason, and that's fine. This is America, that's what makes us great. I have the freedom to choose to stand and others have the freedom to choose to sit. As long as they're not making a bunch of noise and trying to make a big scene and be a distraction, I really don't care what people do. If they want to silently kneel, then fine. I don't pay attention to others during the anthem, I feel that is a time for me to stand and reflect on what the flag, anthem, and this country mean to me. Nobody else.
But that's just me. Live and let live in my opinion. I'm not paying attention to them because I'm reflecting on my own ideals and they're being quiet.
*Edit* I don't know if this would be considered politics, I just saw the post above, but my intention isn't to be political (although I know that everything is politics now days). If so, feel free to delete it, I don't mind.
