I agree that when you read top-level articles about touchy subjects, then you're about as able to predict when you're going to get hurt than when you're going to get bored. I do not agree that it is easy to predict when someone you're having a perfectly reasonable conversation with will suddenly (and often accidentally) say something hurtful -- and this will do more harm and damage in terms of lost time and resources than if the person used a little bit of padding to avoid being accidentally hurtful in most cases.
