I have to agree with you on this fact.
Obviously the apple didn't fall far from the tree in this case and he's upset that this child chose to use a public forum to voice her discontent. Frankly, I'm not surprised that he's not out there publicly flogging her that way he acts. This is a clear case of "he said-she said" and if he acts like this to his daughter, that doesn't bode well for how he treats her mom.

I'm all for punishment fitting the crime. But this is a bit much.

There's a place for this and Youtube is not it.
