Kids are stupid. Although they are over 18 and considered adults, they are still behaving and thinking like kids; they are emotional, without real experience, and are not yet in a position to make sound judgements.
“Kids are stupid.”
And they are in school to learn (become less stupid) more than to express themselves.
From the article:
“Students ... want to discuss things with those who think differently ... but are thwarted by argumentative loudmouths”
That could apply all of us. Thank God for our secret-ballot elections.
