>This reveals right away that you don't really struggle with this issue and just wouldn't get it.
Precisely the opposite. I used to be an "introvert." Turns out I just like to be alone sometimes. Do you really think there are people in the world who don't like to be by themselves? "Extrovert," that's just as much of a myth.
Your argument is that it's more of a spectrum than black and white, and yes, that's surely how things are in real life. You are just much further along the extrovert end of the spectrum than you realize and now believe you get what it's like at the other end, but you just don't.
Spectrum is an oversimplification. Its not a spectrum, its modal. In the same way as space and time are the orders of experience for objects, consciousness has a bimodal constitution in the introvert/extrovert framework, such that extroversion constituitively requires introversion, and vica versa. Its a kind of metaphysics, its the conditions of possibility for experience, not something that can be experienced in and of itself. That’s like saying you can experience time: show me time! Its just a formal term in order to have critical reflections on experience: it is not contained in experience itself! (Except by writing about it).
