Well ex-elder - they weren't ranting - just stood quietly with signs and facts and showing where evidence is to be found. Facts to back it up. JWfacts to back it up.
The sheer numbers will make this a talking point in jwland here in little old UK - those that want facts will go on line and look up the sites in the comfort of home.
Imagine the child abuse victim or the parent of the child abuse victim who was badly treated and still believing. The one who believes that her case was the exception and loyally continues serving the borg.
She sees a hundred people outside her convention stood quietly with their placards. Her mother sees them too. They see a list in the window of a car of all the pedo's.
They check Sewell or Porter or Rose and see it is endemic. Then they see the ARC and they give themselves permission to look deeper.
It's like BUCKEROO - who knows what item will finally make the donkey kick?
WELL DONE JOSEPHUS AND ALL YOUR BRAVE FRIENDS.
