"First of all, there is no such thing as a sex change."
Funny, but I never thought of it quite that way before. You are right, if it were all that simple the dairy farmers could simply alter all the extra bulls and produce a lot more milk.
It's one thing to have oneself mutilated. It's quite another to then claim to be something one is not. As for that nonsense about being a male in a female body or vice versa, what about those who feel they are a young person in an old body or a rich person in a poor man's body, or an Irishman in an Iraqi body?
