Yep. I met his brother. Check this out: At the end of his life Malcolm X evolved and moved away from US-based Nation of Islam teachings and orthodoxy towards World Islam. In doing so Malcolm X renounced the racial essentialism taught by NOI. When he returned to the US from his time in Mecca [where he experienced various races united in their devotion to the faith] he clearly knew that NOI's racial supremacy ideologies related to Islam were a lie.
Some say that he was killed in part due to that found realization.
