> As much as I dislike it sometimes, language absolutely does evolve.

Pointing out that language evolves helps to explain how the current established conventions came to be, but it is not an argument that there are (or should be) no established conventions.

If you are speaking in a way that diverges from what most people understand, then you are miscommunication and are making demonstrable errors precisely because the language has evolved into what it currently is, and not something else.
