I strongly disagree with that. As we grow up we need to be exposed to dangerous things in a safe environment, so that we are not confronted with them later when we have no one to teach us. We are surrounded with dangerous tools (such as stoves, cars, freezers, furnaces, lawn mowers, credit cards, the internet, television, casinos, fast food, etc, etc) that absolutely require training to use. As a parent it is your job to provide that training.
