I'd point out that previous generations were legally allowed to drink and smoke at 18. They were not breaking the law by doing that. If you have laws, and then wink at people who break them, you are raising a generation that has no respect for the law or for people in authority (such as coaches). Don't then complain when those people break laws or rules and then claim they are unfair, and yes, that happens on both sides equally. If a college coach says, "don't party" in the year of COVID, and players party anyway, or if the coach says "don't drink the night before a game" and they do anyway, that is exactly what I mean. If a college student has signed a pledge not do do certain things because of COVID, and breaks that pledge, that is a moral failing. Someone - their parents? society? - has failed to teach them to keep their word, and instead told them, just do what you want, because it's a bad rule.
