Yes, perhaps I could have been less confrontational, but I see this EVERYWHERE and I just can't/don't understand how un-American kids/"adults" can be!
I've had it! I'm usually a soft spoken person with a healthy sense of humor, but I just couldn't stand seeing such a patch.
I can relate.
One time my (former) wife and I were sitting in her parents' living room, talking with her younger sister and a couple of the sister's friends.
They were boasting about shop-lifting from the local Safeway.
I listened for a while, then I exploded.
