Uhm....I can't speak for everybody else, but I certainly don't obsess about weight. Wanting to get healthier and lose weight is hardly an obsession, and honestly I can't see the connection between that and how parents are treated.
Parents are responsible for their kids. If a 6 year old is obsessed about her weight, she must have seen it somewhere. If not the mother, then friends or maybe on TV. Still, if she had been brought up with a healthy attitude towards food, and with parents who make sure that the kid understands what's important and what's not, then there shouldn't be a problem.
If the parents aren't responsible for how their kids turn out, who is? You can't blame TV, because it's parents responsibility to monitor what kids are watching, and talk about it with them. As for drugs - only because there are no drugs in the household, it doesn't mean that the parents couldn't have done more to prevent it. If a kid takes drugs at 10 years of age, something has gone seriously wrong.
As for the kid being left in the car - are you being serious?? If that happens, it is either neglect, in which case the mother won't give a damn if the kid dies or not, or she is completely and utterly stupid, in which case she shouldn't have kids anyway. How can you leave a kid in a baking hot car and not think that it might get a little too warm in there?? In either case they should damn well live with it for the rest of their lives. Plus they should be in court for killing the kid, but that's a completely different story.
I'm just wondering...if we can't blame the parents when kids turn out wrong, who do we blame? TV? Society? Sorry, but to me that's all excuses. If people don't want the responsibility, they shouldn't have children in the first place, as simple as that.
