I'm not speaking to 5th graders, and I expect a competent command of the language for professional positions.
Here's why it doesn't matter what 5th graders think: Take a conservative and a liberal and have them ask a 5th grader to clarify an obvious truth. The liberal asks about war, the 5th grader says its wrong. The conservative asks about abortion, the 5th grader says its wrong, yet hardly any adult shares both those views and fits in line with a party. A position is only as good as the nuanced explanation behind it, and by your standards, both questioners in that scenario would then begin to babble.
I don't walk around feeling like a genius, but you're good for my ego, thanks.
