Okay, real world example - if you're at work or in a public place and you disagree with a coworker/friend, do you: 1) (At least somewhat) calmly explain your point of view, or 2) Scream at them at the top of your lungs and call them every name in the book? Most places prefer that you choose option 1.

That's all they're asking for here.

Good: "You're wrong, here's why."

Bad: "Jane, you ignorant slut!" (2 points if you know where that quote came from.)

Cheers!
