Because my friend,
He beleives he doesn't need to literally wear a flag, in order to be a patriot. That's because unlike you, he's burdened with a complex brain.
However, if you're into easy identification for people with things like lapels, please wear your own lapel that has the number "75" on it, so you alert unsuspecting passerby to your IQ before they have to tolerate your mouth.
It's been a standard for decades, to have the american flag as the backdrop of significant domestic speeches at high levels of politics.
Whereas the lapel phenomenon is a post 9/11 duechbag Fox News commentator obsession, more akin to the passing
snap-bracelet fad, or Cabbage Patch dolls.
Wow, you are truly a very weak, tiny, adorably little brain.
