Interesting timeline! Problem is in order to tie SAD and X together is we have no real idea when boy barry was born. I am not so sure he even knows his real birthday.
Like I said I have no idea who his parents are, lots of speculation, but until the time comes when we see all his records, no one will know for sure.
There is also evidence that SAD was heavy and had no boyfriends in high school, so the likelihood that she hooked up with a married Malcolm X (or Barack Obama Sr for that matter) just after graduating doesn’t seem plausible.
