Maybe that's why you do. Honestly, I think most people stand because that's what we are instructed to do and we would get crap for it if we didn't. We have Memorial Day and Veterans day to honor the troops. I don't understand why the anthem is necessary at sporting events. I don't mind that it's done at games, but if I think deeply about it, along with forcing kids to pledge allegience, strikes me as very 'un American' if you will.
Vegan stuff is an attention seeking behavior? One of the dumbest comments I've ever heard. Well done.
I don't suppose you can back that up with evidence? If it's your opinion, fine, but to state definitively what has actually happened or not happened, you need to back it up with data.
