Wow, people like this make me ashamed to be associated with them. Not all Christians are this ignorant. Nor are they all this vocal. Really, stupid Christians make the rest of us look bad. These are just the ones that, unfortunately, get the most attention. She has the right to raise her kid how she wants, because he'll most likely rebel anyway, but she shouldn't be writing for a blog. They should have some sort of editor there so her brand of shit can't poison other parents.
Actually, I really hope this kid rebels soon and starts listening to rock music, playing games away from home, watching cartoons and other blasphemous arts, because otherwise he'll probably end up just like her.
EDIT: Now that I've read the whole article, I can safely say that this woman is a psycho. I can see why her son is irritable and pale when he comes home AND why kids only spend a few seconds at their place before wanting to leave: because of her. And she will never realize this. But, kudos to the kid for taking baby steps and asking for a Wii.
