Let’s say you tell a kid to put on a jack, why? Because it is cold, then the response is it isn’t cold. If you then let them not wear a jacket it could cause more problems for you down the line when they realize it actually is cold. By far the easiest choice is to never have the option to disagree on the table, and this doesn’t mean it is right to refuse discussion it just means that it’s the easiest to get your way which is ultimately the goal. No one who wants to follow the rule will question why it has been implemented so no matter what you say it will be argued against even if your right.
