So, let me get this straight.
A christian socialist named
Francis Bellamy writes a piece of prose that becomes our pledge of allegiance. Originally, the words "under God" were not in that pledge. And the original salute to said pledge looked exactly like the Hitler-salute of the 1930s:
Pledge of Allegiance - Wikipedia the free encyclopedia
At some point in time before 1942, probably in 1941, someone decided that the regulations for the US Flag code should be applied to the pledge, which means standing up, saluting and saying the pledge. Who knows, maybe they are the same people who decided that the Hitler-salute was prolly not such a great idea, after all.
Essentially, this was a tactic to forge more patriotism during WWII.
Now, personally, I like the pledge.
But some in congress found it terrible without a reference to G-d, so in 1954, the US Congress voted to add words to Bellamy's text - "under God". This wasn't the first time that people tinkered with his text. "Flag" was also changed to "Flag of the United States of America" - with the argument that immigrants would known exactly which flag was meant. Ok, I'm cool with that.
So, a tradition was established during a time a war, one that applied mostly to public schools, but soon, the reciting of the pledge and/or the singing of the national anthem began to be used all over the place. And I'm cool with that, too.
However, it still is voluntary and not mandatory and reciting it or not reciting it has nothing to do with a person's patriotism.
So, to throw someone out of a public meeting for not standing up really does hearken back to the tactics of fascists 80 years ago. All hail the American Taliban!
The Mayor who threw that citizen out is a nutbag.
