NONE of his kids are bi-racial.
Also ... I wonder ... did MJ’s father have him altered when young to keep that HIGH pitched voice. THIS would explain why he couldn’t have kids and had to seek a perm donor. He clearly chose WHITE biological parents for his kids. He also didn’t want to be BLACK.
Interesting theory...however, I believe that it was generally accepted that eunuchs and castrati generally plumped up a bit, and MJ was skinny as a rail. Of course extensive liposuction and/or drug usage could have also kept him that way. It would explain a lot of his psychological issues.
