Sarcasm or clueless? I'm sorry I can't tell anymore.
Let's be intellectually honest here. Our cultural norms (maybe I want societal there?) in this country dictate standing for the anthem is the respectful thing to do. Therefore, doing anything else would logically be disrespectful. We can debate whether or not the intention is to be disrespectful. I think some maybe, some no. That said, norms dictate behavior and generation after generation has been raised to stand for the anthem out of respect. That isn't debatable is it?
