Most of the time. There's a monologue near the end of Team America: World Police that goes further into the nuances of it. Basically, don't be a dick, unless you're talking to an asshole.

Hah, I love that monologue! If we're gonna go from silly to serious though, I would argue that even when talking to an asshole, not sinking to their level is the better solution on so many levels.

I concur.
