I will agree with demanded patriotism being hollow but see nothing wrong with a certain demand of respect for something that is held in reverance.
Like the USA, the Flag, the National Anthem, veterans,marriage, parents, children and our elders to name a few.
I think this lack of respect of a few basic things in our society is a core causative factor for the shitpot we are in today.
Libs seem to gravitate around things that lack in respect.
