Using swear words - why censor?

So this is a conversation I’ve had with my friends recently. She thinks that we should stop using curse words all together. It’s just not proper.

But my view is this: What’s the point of not using curse words when you make new curse words in its place? If I say Frack!!! (<3 BSG) – do you know what I’m saying? Does it change anything? Are you less offended than you were before?

I think the notion is ridiculous.

Also for the sake of this discussion – I mean curse words as a form as expression. (Something drops on your foot – ‘FRACK ME!’) And not curse words as a means to insult. So please don’t get on the notion that I’m saying using curse words to insult other people is proper – because it’s not. This conversation is more about the everyday uses of curse words such as “Damn I forgot my keys, and my spare is with my girl. I’m fucked aren’t I?”
