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.
Having the same shared traditions matters because they create unity greater than your immediate local area. It's leftist inversion to suggest maintaining a tradition's integrity is a weakness. If it was, then why would one of the first things leftists do is undermine them with "fun" variants/deviations?
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.
