The Flag Code says what it says. You might consider it to be hopelessly outdated; many view the Constitution the same way.
I will continue to show respect for the flag, even if that makes me “senile or stubborn”. You may do as you please.
Once the Supreme Court declared that it was a free expression of protected speech for our nation's flag to be desecrated and burned, both the spirit and letter of that law became completely moot.
many view the Constitution the same way.
That's a silly and fallacious non-sequitur argument. The Flag Code was effectively invalidated through what was ostensibly a constitutional process of judicial review. Your attempt to conflate the two is both illogical and a little humorous (at your expense).
I will continue to show respect for the flag, even if that makes me “senile or stubborn”.
Your criticism of this girl's patriotism has nothing to do with any respect for the flag you may or may not show. There are anarchists and communists defacing and burning the flag every night. How much public criticism have you leveled here against them? Instead, you attack a young girl's patriotism. Whether or not you actually are senile or stubborn, your action is shameful.
You may do as you please.
You are contradicting yourself. You quoted a law that falsely portrayed this young lady's actions as being illegal. Now you are saying that that there are no restrictions?
There are many ways to respect the flag that don't involve adhering to a completely antiquated and invalidated regulation. This beautiful young women wanted to publicly show her love for our nation. Anti-American leftists in her school and curmudgeons like you are working together to undermine her effort. You should choose your allies more carefully.
