No it's not. Standing for another country's anthem in no way shows any disrespect for my country at all. Please, some sanity here.
Absolutely not! When there is respect and your own flag is present is your own country, it is fine and quite respectful.
Do you remember when our soldier climbed Saddam's statue when Iraq was torn down? And then our soldier put OUR flag around Saddams neck, and the entire area went quiet? Fortunately, they realized the faux paux and replaced with the Iraqi flag. How right that was!!
Flags mean something to most of us. When you fly someone else's flag and not along side your own, it means you are conquered. As I understand, there was no American flag. Very bad principle to teach our children.
