I stand up yes but the hand over the heart and the singing out loud not so much.
In Canada we don't have to wave a million flags to get attention. Oh and if its a
foreign delegation type of event I stand up for that countries anthem too out of
respect. This gushing patriotism nonsense is much overdone by our friend to the
south.
Patriotism is not ascendant in the United States. The country is breaking into mutually hostile tribes divided by both culture and creed. Imo your understanding of the US is outdated. You remember the Old America. It's gone and will never be restored.
