"You don't get to pick the language other people speak. " And yet that's exactly what you've done, when you've decided the meaning of another person's speech. You say that "it has a meaning and a connotation", but both the connotation and meaning depend on context and speaker (and also, as you've noted, on listener). It's simplistic to think that the only meaning of words is your interpretation. In a presentation, speaker and audience may interpret what the speaker said in different ways. And your notion that "all of us English-speakers have agreed upon is laughable" - I would challenge you to visit a culture outside your own. Hell, just watch The Wire to see how wrong this idea is. I'm not sure whether you noticed that "I'll interpret the words the way I want to" directly contradicts "You don't get to pick the language other people speak". I wouldn't say that profanity shouldn't exist, merely that "fuck" in its modern usage is not profane. If you disagree, I'd challenge you to find a profane translation of "get your fucking attitude out of my language". It conveys aggression, but it's hardly profane.
