I guess I don't get the whole internal struggle with "gender identity". You're either male or female. Regardless of how you "feel", you're either male or female. You may not like your gender, you may not "identify" with your gender, but you're either male or female. Through modern medical technology you may even be able to change your plumbing. But you're still biologically either male or female. Chromosomes don't lie.

(OK...for all you who want to argue specifics of chromosome abnormalities, I'm referring to normal genetic makeup...not the relatively rare exceptions to the human male/female chromosome arrangement.)
