“Because he was the one and only Bari Malik Shabazz who lived very close to his father Malcolm X AKA El-Hajj Malik El-Shabazz, a man who gave the name Shabazz to his wife and acknowledged female children.”
Bari Shabazz wasn’t the child of Malcolm X. He was born Barrington Hughes, in Kingston Jamaica, and then changed his name to Shabazz later in life, most likely after moving to New York and converting to the Nation of Islam. You may not know this if you are not familiar with the NOI, but “Shabazz” is an extremely common chosen surname for converts, probably second only to “X”. There are thousands of people named “Shabazz” in the NOI, and very few of them are related to Malcolm X.
“Seems likely to me that he was born in Kingston Jamaica under a false name to hide his parentage.”
It seems likely to me that this is a great example of circular reasoning. The only reason you have to suspect this fellow is that, before we found out who he really was, some people speculated he was the secret son of Malcolm X, and an alias for Barack Obama. Now that we now that isn’t true, you don’t want to let it go, so you are coming up with the idea that he was born in Jamaica under a false name to prop up a theory that is shot full of holes. You don’t have a shred of evidence to support that idea though, so it’s safe to dismiss out of hand.
