Wanted to smack the kid!

The biggest "problem" we face sometimes is that there are people out there that don't know what you know. And to you, it seems like stupidity but it's not, it's ignorance. Ignorance isn't necessarily a bad thing, it only means that you don't know. Don't confuse ignorance for stupidity. The young man was ignorant of what MOPAR meant. Stupidity would have been smacking him and getting arrested for battery.
