C'mon, guys! LaToya and MJ ARE the same person. It's called fully-transformative split-personality disorder. Instead of just being two or more people in the head, the body actually takes on the form of the identities. This phenomena occurs during ritual satanic abuse, where the victim taps into the power of their most primitive cortex, reshaping their bodies in primordial-ooze instinct, thus allowing them to camouflage their bodies and escape their attackers. We all know MJ was from a broken home, and he even admitted himself (in that tell-all interview) he used his imagination to escape - but even he knew not how far! LaToya is rarely seen with her family, and they are always reluctant to speak much about her, very much like an embarassed mother is loathe to discuss her child's only friend - an imaginary bird.
We must not badger MJ, we must not ridicule him. We must help ween him from his childhood escape-route. Can we find a way for him to comfortably merge his innerselves? We must rally around the poor child crying out for what he most desperately needs, and we must find a way to convince him it is for the sake of all that is beautiful, all that is pure, and all that is innocent on this forsaken plane! Give him a sex-change!
