Whether he takes away privileges or not is irrelevant to the actual parenting issue.
In previous posts, you had made several statements to the effect that threats and punishment being bad parenting. These are withdrawn, then?
Now, if you're just complaining that you think the father was taking action irrationally, then try and say just that; don't make it look like you're against the very notion of discipline, or that you think destroying the laptop is an inherently inappropriate punishment regardless of circumstance.
But...
his method of revoking privilege
You do seem to explicitly state that that the props are important. That, regardless of the circumstances involved, shooting the laptop is inherently inappropriate. If that is true, then you need to discuss that point
on its own without getting it all confused up in the other aspects.
Anyways one thing I want to point out:
The father was visibly shaken and his feeling were hurt by his daughter's words. And his choice of words further demonstrates this.
demonstrates ... it's okay to destroy people's possessions in anger.
Taking action in anger is a
very different thing than being angry/upset while taking action.
Going through with the punishment was clearly very difficult and upsetting for him. But that doesn't mean it was done
in anger. In fact, the main feature of the punishment is described as being selected beforehand during "amicable discussion".
