Cause if you don't wear one, then you're obviously not patriotic. Oh yeah - except for the guy who's saying that Barack Obama is unpatriotic for not wearing one - who isn't wearing one. But he would wear one. So that resolves that issue.
Silly political crap. Although, a woman called into a radio station I was listening to yesterday and felt that Barack Hussein Obama was working for Al Qaeda and part of her proof is that he doesn't wear a flag pin.
