Why are so many JW Celebrities black?
Because the The Jackson family made being a Jehovah's Witness look cool.
It all started because of a JW Mom named Katherine Jackson.
From eldest to youngest: Rebbie, Jackie, Tito, Jermaine, La Toya, Marlon, Brandon, Michael, Randy and Janet.
In the end only Katherine and Rebbie remained Jehovah's Witnesses. Wikipedia puts Katherine as 94 years old with no mention of a death date.
