A product of my upbringing after all....

Sometimes I wonder if my political and social beliefs are adapted specifically to be contrary to prevailing public opinion, or whether I really am that far out of the mainstream.
Case in point-- Apparently, Jim Cornelison's rendition of the Star Spangled Banner at last week's Bears playoff game against the Seahawks became a YouTube sensation, which seemed understandable given that the vast majority of the fans were cheering, beers in hand...throughout. I would have thought that "normal" people would have been appalled at the disrespect shown to our anthem, but....as usual.....I would have been wrong. It's a tradition at Blackhawks games, you see, and now they've decided it should become a Chicago all-sport tradition, I guess. I grew up with the understanding that the singing of the National Anthem was a solemn affair, and have been offended for many years by the "interpetive renderings" (think Roseann Barr) that have become fashionable, but this latest trend seems to mirror the faux patriotism so much in vogue. (flags on cars, lapel pins, etc etc) I was curious as to whether there is an "official" etiquette, and was suprised to find that, in fact, there is a specific policy in the U.S. Code---

Sec. 301. National anthem
(a) Designation.–The composition consisting of the words and music
known as the Star-Spangled Banner is the national anthem.
(b) Conduct During Playing.–During a rendition of the national
anthem–
(1) when the flag is displayed–
(A) all present except those in uniform should stand at
attention facing the flag with the right hand over the heart;
(B) men not in uniform should remove their headdress with
their right hand and hold the headdress at the left shoulder,
the hand being over the heart; and
(C) individuals in uniform should give the military salute
at the first note of the anthem and maintain that position until
the last note; and
(2) when the flag is not displayed, all present should face
toward the music and act in the same manner they would if the flag
were displayed.

I guess it doesn't specifically state that "You should not behave like a drunken lout", but it's intent is clear.
It seems odd that a left-wing commie like me should be offended by the disrespect shown to our flag and National Anthem, while all the "Support our Troops" and "United We Stand" folks are not. When I mentioned it on Facebook, it was interesting to see who agreed with me....virtually all of them were either ex-military, or military brats. We were raised (or trained) better than the rest of you.
