Answers.
1. You are a disembodied brain, not a person. To be a man or a woman you must be a person. You, as a brain in a jar, may very well be mistaken that you are still the person you once was, just as the Japanese soldier in the jungle of The Philippines in believing that WWII was still raging, but you'll be objectively wrong.
2. You are launching a Ship of Theseus argument. Suppose you are a man and you suffer from renal failure, and a female kidney is transplanted in you, are you a man or a woman? How about also replacing your heart with a woman's heart, your lungs with a woman's lungs, your liver with a woman's liver? Where is the point, if any, that you stop being a man and start being a woman? Ship of Theseus scenarios ultimately have no generally accepted resolution. I don't think the sub-questions (a) and (b) are of any relevance.
3. The scenario is not clear enough. What does "changing a biological male into a biological female" mean? If, because the writer mentioned "every last chromosome", I interpret it as "changing each and every cell's sex chromosome from XY to XX". then it sounds like a Ship of Theseus scenario like (2) ("What if I change just one of your cell from XY to XX? One hundred cells? One million cells? One trillion cells? Half your body's cells? Half your body's cells plus one? Every single cell but one? Literally every single cell?") but with an important difference: organ systems are developed in utero; changing the sex chromosome of the cells in the fully developed organ of a grown human will not change its structure and function. Your fully XX penis is still a penis; you are still a man.
So my answers -- and note my arguments are purely Biology based, no considerations for "psychological state" or "socialization" -- are:
1. No.
2. Undecidable.
3. No.
I'll bite and answer these, too.
1. A brain in a jar is a person, but not a male or female person. You need a sexed body to be male or female.
2. You'd be the sex of whatever body you'd be put into. As for whether I'd be comfortable with it, you're asking a question that doesn't pertain to trans people at all. This is because we're naturally going to be uncomfortable with what we're unfamiliar with. Trans people are not in a situation where they got transplanted into a different body or got transformed into some other creature by an evil enchanter/enchantress/whatever as in the fairy tales. They're people who have always had their own body, they just don't like it. Just like most people on Earth who complain about their bodies.
This is a disingenuous attempt to get people to say, "I wouldn't be happy being put into a female/male body because that's not what I am." In reality, people wouldn't be happy because it's not their body that they're already used to. What if this new body isn't healthy? What if it's ugly? What if it's very old or very young compared to what you're used to? What if it's obese? There are so many variables in this hypothetical that it makes no sense.
3. If you actually could make a man into a biological woman, then he'd be a she. I'll concede to that one. However, that's not possible to do. You cannot fully change a man into a woman, all you can do is give him certain secondary sex characteristics (which aren't primary, which is why we don't use them to determine sex) and hack off his genitals.
Also, I doubt that even if you managed this fantastic brain transplantation or fairy godmother transformation that you'd manage to overcome the AGP that drove you to begin with. To that end, would you even get such a procedure? You wouldn't be able to jerk it anymore, so I doubt it.
To continue on, I argue with his neurobiology = brain sex, and trans people totes have a brain sex. I posted this yesterday and I guess I'll post it again here. Neurobiology is a form of neurosexism, so technically you don't have a 'female brain' because we can't even quantify what that is.
And, for his final point, no, trans people aren't changed enough to be considered intersex. That's not what intersex is and that's not how intersex conditions are caused. An MTFer isn't just like a man with androgen insensitivity.
And I notice he's leaving the poor pooners out to dry in his analogy here. Then again, they always forget the pooners exist.
