RC, you've argued with me previously that "chair" has no objective meaning. How can you possibly have one for "railroading," even kinda-sorta?
Terms are always nebulous. That this is so limits their value, but doesn't make them valueless.
If the term "chair" has no objective meaning, neither is its meaning entirely subjective.
When one argues that a term is useless unless it can be pinned down, one is going to discover that no term can, in fact, be pinned down. The usefulness of terms is not, when all is said and done, based upon our ability to agree concretely upon their meaning. Or, if it is, then all terms are useless.
Hence the "kinda-sorta".
Tell me that a term is too vague to be of use, when I and many others obviously find it to be useful, and I am going to point out that vagueness is endemic in language.
Tell me that a term has no meaning whatsoever, and I am going to point out that terminology has meaning beyond that which is merely subjective.
Philosophies that claim that everything is subjective, or that things can be objectively known, miss the mark, IMHO. The limits to objective knowledge do not require everything to be therefore completely subjective. Nor does our subjective impression somehow destroy objective reality.
There is a median ground between "objective" and "subjective". That median ground where we all live. IMHO, it is about time that we get used to living there, because it isn't going to change.
Again, IMHO. YMMV.
