Yes and, I hate working with people who think this means you can literally say “you are stupid” and that this the same as providing helpful feedback.

If you are blunt to the point of being rude, then any communication you’re attempting is going to get lost behind the other person getting angry. People, generally, don’t think productively if they feel attacked, diminished or insulted.

You’ve gotta phrase what you want to say in a way that won’t elevate someone’s emotions beyond the point that they can actually hear your real feedback.
