I think that video was a lot more about her than it was about him. His tone was condescending. He mocked her attitude (which, believe me, is a crap attitude) in front of now almost 24 million people. Yes, I think that's in the realm of cyber-bullying. Tit for tat is simply not the way we should parent.
