What bothers James Lileks about gutter language in the public square seems to be the fact that "there's a small child present":
If naughty words crossed my lips, they would not necessarily require a road map. And, of course, that makes me an utter hypocrite, I suppose. So, you can say it at home, but Bono can't say it on network TV? Yes! You've grasped the nub of the gist, you have.
What bothers some of us, though, isn't the doggy doodoo connotations of gutter language per se so much as the poverty of language resources its excessive use betrays.
