I've always been a big advocate of the idea that the only part of communication that matters is communication. If people understand you then congrats you've successfully languaged
That's their problem. I always assume the stupid people are the ones that are so inflexible and uncreative, that they don't understand that language is entirely an amorphous flexible human creation.
The flip side of that is that if the words you're using are wutdownrerary, you should be told to stop using those words because by using them you make communication harder.
