I appreciate your thoughtful comment.

The essay got rather bloated trying to address all the possible counter-arguments, the scientific research, and the potential caveats; and despite my efforts to tone down the moral grandstanding, a lot slipped through. I should probably re-write it as a shorter essay with a thousands footnotes, "Why I Don't Swear".

Always worrying about it wouldn't be healthy, but to me it seems like a good idea to at least consider the potential negative effects self-expression may have on others, and weight that against the benefits of self-expression.
