Yeah, its YouTube comments - not a scientific poll. That was my point. I'll say it again, most parents don't discipline their kids on youtube for the sake of their family and their kid. And in regards to general public discipline, most of it doesn't take the form that this guy took. The fact that he never intended it to go viral means nothing - it means he's ignorant of social media.
Anyway, I don't really care that much one way or the other, just saying that girl's relationship with her dad probably won't ever be the same, and traumatic events like 12 million people laughing at you and your family certainly tend to lead towards more rebellion and erratic behavior.
Additionally, the dad's entire life will be known for shooting bullets at a laptop - congrats, buddy. But I'd mostly be concerned about the after-effects of a large social media event on a young teenager that was caused by someone very close to her. Psychology was one of my majors in graduate school, and social trauma + youth + family member is a bad combination.
