its not a man. no matter how much drugs and operations she has, it will always be a woman.
You say that because Sonikku shoved her in your face as a woman, and genetically it's true. But practically speaking, you wouldn't pull out her chair, or open the door for her. If looking around a room for a woman to approach for possible romance, you'd skip right over her. You wouldn't consider her an ugly woman, you'd consider her a man. And in every way that matters*, she has become a man. SHE has become HE. For him, there is no possible way to even enforce this stupid law.
* I specifically exclude G-d and genetics. The latter I can't see, and the former . . . Well, He's a big boy (or girl), He can take care of Himself, and if He has any views on the matter, He hasn't seen fit to share them with me. Assuming this newly minted man is happy with himself, I like to think G-d is happy for him. To believe otherwise is to say that G-d created him as a woman who feels herself to really be a man, but He wants her to stay just as He created her, even if that makes her miserable. That would make G-d a dick. Please don't call G-d a dick.
