I have seen the Williams sisters, Venus and Serena given a bad time alternatively about not being "good" witnesses and not being baptised yet (at their advanced ages).
I don't see that the association has clipped their wings any. I wonder why they make the claim at all? Beautiful girls, very skilled, very imperfect....I am thinking baptism will happen when they retire and are out of the limelite.
If my dad was gonna push me, Id sure rather he was pushing the part that would make me a world class tennis player rather than to be a drone JW. I think the Williams are JWs like many Jews are "Jewish.' That's what they were born into and they don't eat bacon on the Sabbath.
