Suppose my child asks when she's going to get fur. If I don't know what she's been reading, my first thought might be that she saw one of her friends or a rich old lady wearing a fur coat and wants one for herself, not that she doesn't know that humans don't need fur to stay warm like dogs do. If I then begin explaining that raising or (worse) hunting wild animals for their fur is unethical, but I'm happy to buy her a nice synthetic jacket if she wants it, that doesn't mean I'm an idiot who doesn't even know humans don't grow fur and Everything That's Wrong With Society Today, it means I misunderstood her question.
