Found this on the subject: And I think i agree..
There are a few interesting things on cursing and so called "bad words" that I would like to share:
First of all, cursing is the only thing where it's okay to do what you are describing but not say what it is. Nothing else is like this. It's okay to say "murder" but not okay to murder; it's okay to say "rape" but it's not okay to rape. Yet, it's wrong to say "shit" but it's okay to shit.
I remember my parents got upset once when I said the word "fuck" to which I responded, "Hey, I'm just saying it, you actually did it." So why is that?
Why are bad things good words and good things bad words? Rape is a bad thing but a good word and shit (or fuck or ass) is a good thing but a bad word.In fact, not only is it okay to do the things the curse words describe if you don't do it life will end.
Try not to shit. Never ever shit or piss and the result will be that you will die. Likewise, fucking creates life; if no one ever fucked the human race would become extinct. I think the F-word should be famine instead of fucking. Famines destroy life and fucking creates life, yet which one is considered the bad word?
If it's a good thing it should be a good word. Why are the worst things--famine (the f-word), cancer (the c-word), war, murder, rape-- "good" words but things that unite us (like shitting) or create life (like fucking) considered bad?
