Funny thing is, she SOUNDS like a parent admonishing a child...particularly like a parent who doesn't have a good answer when a child asks, "But why?"
I have to admit that I am one of the people who has gotten her upset, as I have asked very polite questions of her minions and had them struggling to find rational answers. When she came over and whispered (presumably, "don't respond") to her underling, it put her in a bad situation, as it was obvious that my questions--left unresponded to--were getting through to third parties walking by.
That's their weakness...rational thought. The rely on irrational emotionalism for success, and they can't afford getting into a rational dialogue. This is another reason why they try to provoke violence and get our side to stoop to their level.
This admonishment from Karen came out after I posted this interview with a peace-protester:
