He has not as far as I know. I was just trying to illustrate how gender politics has transformed the even more of the language associated with this issue. If I understand your position correctly you should not have to change your pronouns even after surgery. The biological sex will not have changed.
yes, "confirmation" is ridiculous.
you are correct that i think the most accurate pronoun in the correct one to use. i'm quite confident that the male pronoun is more accurate, currently. post surgery, i'd be less confident. genetically the organism would still be male, but we don't directly perceive an organism's genes. hormone treatments would cause many of the organism's characters to express more as female than male. most (all?) sexual organs would be surgically changed to female or a reasonable facsimile thereof.
we refer to neutered animals as male. we refer to eunuchs as male. however those are organisms that have merely had the testicles removed. no attempt to replace the male sexual organs with female has occurred.
i'd want to think about it in more detail, but i think the female pronoun is probably the most appropriate, all in all.
