>When will it stop?
It won't stop while there is breath in her body. She has one idea in her head and nobody is going to disagree with her without getting a mouthful of abuse, as she clearly thinks everyone else in the known universe is intellectually inferior to herself.
With any luck, she will realise that (almost) nobody is listening and go back to her - well, I nearly said 'research', but she doesn't appear to actually do any, just rubbishes everyone else's.
Perhaps if we all just tiptoe out of the room, she can just rant to herself?
