I don't think any of this can be quantified. At some point, all we are left with is how we decide, as a society, to draw up the concepts.
Do we go 100% subjective? = You are who you feel.
Do we go 100% objective? = Boys have willies, girls have fannies, and there is nothing more to talk about. "Oh that one? I guess that one goes under miscellaneous. Oh, you used to have a willy, and now you have a fanny? Okay, you are now a girl."
Do we go intersubjective? = Well, France exists because we agree it does, and the People's Republic of China exists, because we agree it does. Tibet? Sorry, you are not really a country are you? Taiwan? Well, look, you can be in the Olympics, but not in the United Nations. Sorry, look, you're outvoted on that, now sorry, I know it's awkward but we can't please everyone.
