This is when flag waving becomes frightening to me...

In Massachussettes, a pizza shop owned by middle eastern immigrants was burned or bombed or something. The other people in the neighborhood said it wouldn't have happened had the pizza shop owners displayed their American flag more prominently.

I would call that mindset rabid. Rabid flag waving has no place in a democracy if it causes people to fear for their safety if they don't prominently display an American flag.
