Sorry, I think that's somewhat silly. Black, so far as I am aware, is a colour, as is white. Now, I know of no humans at all who actually have black or white skin. Various shades from dark brown to a little bit pink, yes, but no true white or black. At the end of his life, MJ was a male (he kept that part the same, so far as I know), but his skin colour was definitely around the same shading as what we call a "white" person. His ancestry, his parents and brothers and sisters may all have brown skin, but MJ does not.Remember Michael Jackson? He was Black. He went to a lot of trouble and expense to make his skin look light and his hair straight. He was still Black. A man can go to great expense to grow breasts and long hair, etc, but he is stil a man. He might feel better but nothing changed.
And really, to say that in the case of a person born with a penis and testicles, who now has breasts, long hair and a vagina (what plastic surgery can accomplish these days!) "nothing has changed" seems just a bit ludicrous. Lots has changed. Maybe not naturally, but changed none-the-less.
