Subjective v. Reasonable Objective:
The subjective is what a person actually means internally. The reasonable objective is what an ordinary reasonable person would assume the person means based upon their observable conduct.
The subjective is unknowable and any system that tries to make allowances for it will fail because of its inherently unknowable nature. Even if the person tells you they can be lying. Thus we can't use it.
The reasonable objective is entirely knowable by its very definition. I say the word "cat" the ordinary reasonable person thinks I am talking about an animal that meows, purrs or otherwise is a freaking cat. This is entirely reasonable for them to think and I know that they will think this. The fact that I might say the word "cat" to refer to a barrel of oil, or anything else within my mind is subjective and doesn't matter/can't be used and I know this.
Thus, what the objective reasonable interpretation of a word's use is, is the standard to be used.
When you use a word that the objective reasonable person would understand to mean one thing, that is what you will be assumed to mean and that is fair. It is fair because you know what will be thought in the minds of others with you say a certain word.
Summation:
If you say a word that is commonly understood to be derogatory, then you will be held to have used it in its common manner until and unless you prove otherwise. If you fail to meet the burden for proving you did not use it in it's common, derogatory way, then that's your problem.
You are aware of the ordinary, common use of a word and are held to have used it as such until and unless you convince your audience you did otherwise. Good luck with that. Symbols or not, you know what people will reasonably think you mean. That said, it's on you.... Deal with it.
O I'm sorry, by "deal" I subjectively meant "vomit" but you understand right? And hey, everyone should get my subjective internal meaning and context of the word "deal" to mean "vomit." Right?
Communication on a large scale doesn't work any other way....
