The thing is, there is a difference between males and men. Male refers to physical sex, and men refers to mental gender. Therefore, a pre-transition MTF is a male, but not a man. You see? I desperately hope you've figured this out by now without my help, as the column is five years old.

If Riam hadn't said it, I would've said the same thing. While males are usually men, they're not always, and vice versa. Male is the physical sex. Man is the mental gender.
