I'm a Baltimore Orioles fan. During the National Anthem our fan base will stress and yell out the O in O say, does that star spangled banner yet wave.
You guys think this is okay or disrespectful? My brother is an Air Force vet and doesn't like it. I don't have a problem with it. I've heard that Braves fan highlight the word Brave.
People who get hung up on minutiae like that will be the first to demand everyone fall in line behind the sending US troops to Ukraine or Israel, or sign up to be the neighborhood snitch next time there's a lockdown.
Shouting out your sports team or your community or even your Scout troop's name when you're singing the national anthem is the sign of a healthy nation made up of robust communities. It's a signal that you understand what your sense of nationalism is built on. Insisting that the symbolism of the anthem itself needs to be rigidly separated from those things is not a sign of virtue. It's a display of weakness, because it means you think the symbol is just a symbol, supported by nothing of value. It's an empty virtue signal, an appeal to authority, and it betrays a deep insecurity.
I don't agree that shouting out different sports teams while singing the national anthem constitutes different traditions, or that it undermines that tradition's integrity. I think it strengthens it, because it highlights the basis of the sense of nationhood that the anthem provides.
