I think a lot of advice tends to be an explanation of a social rule, with the implication that following the rule (or "masking better") is preferred. Sometimes the insistence that rules must be followed is more explicit, which I find aggravating because I don't think social rules have to be followed, and there are many times where they should be broken. I think they're similar to literary or grammatical rules in that it's better to be aware of them and have a nuanced understanding of how people use them, so I can follow or break them more intentionally in conversation as my preferences dictate. For my money I'd rather people take the time to explain the rules they adhere to no matter how silly or damaging they are. At least then I can engage with the rule more tactically rather than being caught unaware when I accidentally break it.
