You're judging him based on your culture, and preconceived notions and not knowing the other side of the story. We do only see one side and also what may be acceptable in one part of the country or world may not be in another.
My point is that there are lot of criticisms about how he's handling the situation, some of the criticism I think is valid and some I would disagree.
I also think a lot of criticisms come from non-parents and until someone becomes a parent people have no idea how hard it is. Personally, I was guilty of this before becoming a father, now I see the difficulties.
I don't own a gun, and I don't think shooting something is the greatest thing, but I can see what he's trying to do and that is change his daughter for the better. I'm also from part of the country where gun ownership is not a huge thing, where as people from the south and west do own guns and its a totally different culture.
So you need to be an American parent to have a valid opinion? I don't think that is a necessary qualification to identify a redneck attention whore on a power-trip.
