He didn't advocate blowing smoke into a child's lungs. He advocates taking care of their own children and when parents "take care of their children" they protect them from certain things. You have completely twisted this man's words. And for that, I resent it. Get the words straight before you feed into them, ok?
It was a woman who made this stupid statement. And a parent who smokes around children is not "protecting them" from harm, it is inflicting harm on them.
