To determine the meaning of every word as they've ever been and attempt to remove any that have ever been used in a way that could've upset anyone ever, just makes sure those words will continue to upset people and be painful. There are words with stronger denotations that would take generations to heal but these are words and concepts that the children of today might not even recognize. Should we attempt to solidify pain by hiding truth? Or would it be better to let the youngins change things the way they always do.
If you take their words, they'll just make more. And those new words will not have the ambiguity of our current language.
