I saw part of this case. And Michael definitely was not the better parent. Michael left the "wife" and chidlren for another woman. And just because Michael underwent body modifications does not make "him" a male.
What about those peope who have plastic surgery to look younger, who have a "young mind in an old body"? Surely the next step is for them to claim a new birth date.
Or how about the converse - an old mind in a young body. Could be grounds for qualifying for early retirement benefits at 30 something!
Oops, gotta go... My University of Michigan Law School application is due. I think I'm going to be Zimbabwean today.
