Imagine I said “That Volkswagen Jetta is blue.”
Now imagine someone popped up to say “No, that Volkswagen Jetta is a stylish yet surprisingly affordable compact sedan. Buy or lease one today from $16,720.”
And I said “That’s not what I was talking about.”
And they said, “You said ‘Volkswagen Jetta’. That’s a compact sedan. It’s not a color, it’s a car. Cars and colors are different things. How can you pretend that they aren’t?”
Would you agree with them, or disagree?
In the sentence, “My penis is female”, the subject of the sentence is referring to anatomy. But there’s no transitive property of language that causes that to permeate the entire sentence. Like, if I said… to switch parts of anatomy… that my hand is raised, we don’t have to search for an anatomical definition of “raised”, because that’s not what the sentence is about. If I say “The boat is on fire.”, we don’t have to know a special nautical definition of “on fire”. The syntactical subject of the sentence, in other words, doesn’t “theme” the entire sentence… which is a point so basic that it shouldn’t need to be made.
One of the functions that the word “female” performs in everyday English is to stand as an adjective relating to the noun “woman”. I’m a woman, so the female adjective can be used to describe me. Trying to argue against this in specific cases is nothing more than playing semantic games to argue against my womanhood through less obviously direct means.
