MJ is not the only person in the world with vitiligo, its quite common, besides its only hearsay that the son has it. I don't believe for a second that any of the kids are his biological children, they were all engineered to order.
It's not only hearsay, Prince's family members & his girlfriend have all said he has it. And actually, vitiligo is not common at all, it affects less than 1% of the population. The likelihood that MJ ended up with a kid that is not biologically his and had that exact same disease is so unbelievably slim. Not to mention people with autoimmune diseases cannot donate sperm.
Are you kidding me?
Genetically engineered his kids? Genetic engineering is still only in trial stages & even still is only used to prevent diseases not to pick & choose physical traits. It didn't exist in '96.
