I am not a parent, so I'll admit a skewed perspective here, or perhaps a lack of context entirely, but I think you need to be
very careful about putting forth authority -- what I assume you mean as discipline and respect -- as a sufficient basis for different standards of behavior.
From watching people grow up in my generation under the same sort of philosophy, I've seen them develop the mind set that anything put forth by authority must be correct, and in the process hold obviously contrary points of view without batting an eye. One of the causes I've been able to gather is that they spent a large part of their growing years being told how things are and to accept that as sufficient evidence, but not having what is asserted jive with their own impressions. Enough of that, if they don't rebel they develop the sense that their own impressions and intuitions are completely flawed, and should never be trusted without someone else to tell how things are.
I'm not saying that you are wrong to enforce a no swearing policy with your kids -- that's an entirely different discussion that you have already said you don't want, so I won't push for it. But from my teenage perspective of not so many years ago, I can imagine being very different -- less curious, less assertive, less independent -- if my parents had been more authoritarian, and not to be harsh but less reasonable, approach to setting ground rules for my behavior.
