I agree that she was absolutely correct not to mention Catherine in her bullying panel thingy.
She would have looked a bigger hypocrite, if that's possible, than she already does. All her be kind, make SM a safer place, is just lip service, in her case.
The less that comes out of her mouth about Catherine, William and their children, the better it is for everyone. They have said more than enough.
But they could have said they do not condone the things being said by the likes of Scobie, Bouzy, etc., everyone would know what they were distancing themselves from.
