"Multicultural Competence" isn't a buzz word or an obfuscation here, it is a survival skill--

The skill is important, indeed essential - but words like that get in the way.

Far better to take a bit more time and talk in terms such as the skill of recognizing situations where someone isn't familiar with what what is going on, and developing a strategy for bridging the gap

or being able to see others as they see themselves, as well as understanding how they see us.

If people say they disagree about the importance of doing stuff like that, you know there's a real disagreement that needs to be tackled. The kind of arguments that are thrown up by jargon terms can enable those kind of disagreements to camouflage themselves.
