What's the big deal?

I had my shoutout in MSN stated 'I'm so fucking uptight'.
Then, a friend of mine came and said to me that,'Put something else lar. Like farking.'
Well, it gave me a lift on my eyebrow.
I'm not trying to say that cursing with the word FUCK is good or cool.
I mean when one is depressed and angry, the sanity is gone *PUFF*, all kinds of language and word are release from the mouth.
By substituting the word FUCK to FARK, sounds so hypocrisy to me. It's just an expression to me.
I had no intentions to use it to scold or curse on one person.
To guys, it may sound rough and rude for a girl to use it.
Please...guys are just...oh my...what kind of century is this????
Still forbidding a female to swear?
Then, what about guys who swear?
They think they are macho when they swear???
In a girl's mind, they go,'This guy swears a lot. Oh my, how am I suppose to judge him?'
So, to be fair, let's swear. But, please be aware of your surrounding when you swear.
Try not to influence a kid who is under 15 of age to swear earlier. Not good.
Oh, by the way, please use those words with limit to avoid unnecessary 'SCENES' for the crowds.
Use it in a matter of humor.
Plus, I don't swear that much. I've my limits on some words.
