Your semantical argument of "principle" vs "contextual rule of thumb" is incorrect. They mean the same thing in almost every context, according to any dictionary/thesaurus you find out there.

In fact, the ultimate defining characteristic of a "principle" is that it has exceptions and should not be used as the "ultimate word of God".

Even in Physics, where most would think a "principle" means something "without exception", they are only ever currently without exception according to current evidence. There has been countless times where there has been a scientific principle only to be disproven later on.

Lastly, you link Sapir–Whorf, which, quite ironically, is considered a "principle" yet has had much criticism over time, which contradicts your own argument.

However, I will agree with you that one should always be careful of the language they use since it can affect how others view your thoughts, feelings, and intentions.
