The problem is that language is not set -- it changes over time. And context makes a difference. What
helios argues does happen, though not always under the same context, even for the same person.
All language comes from a common understanding.
That's why we (and all cultures) have a common "elevated language", if you will, so that people can try to communicate without giving offense, and treat "vulgar" (or common) language as generally tactless.
People always have a hard time being mistreated, no matter the word used, and regardless of the intent.

So would shouting "Ow ow ow owwie!" or even just screaming. It is rare for people in instant pain to make conscious decisions about their vocabulary.
I also disagree about the football match. The people sitting in front of you might think you ought to obey some public profanity laws -- and whether reasonable or not -- you are still forcing them to hear what they would prefer not to in a public place -- a place they should have an equal right to enjoy.
Which brings up an interesting point: You have a private right to do all kinds of uncouth and horrid stuff. But people somehow believe they have a public right to the same. The less civil public discourse, the more antagonistic public interactions.
Can I buy a ticket to the football match in a seat where cussers will not be? Or does the venue specifically require me to defer to those who think they ought to be able to subject my ears to overtly offensive language? In purchasing a ticket, am I waiving my own convictions to those who don't care? That's kind of one-sided, methinks.
