IMHO, I try not to curse so much because I have to be mindful of my audience. People can't just say what they want and expect smooth sailing. Especially in real time chat. Unless people find you charismatic or something, I wouldn't want to give people the wrong intention.
I understand being yourself, but certain peeps need to put a lid on profane language....especially if it's a habit.
Nothing can go your way until the intended audience is cool with you. No one wants trivial and petty things to come into play. So why take on the "I can say what I want and everyone can shut up" role?
If I were to take that route for instance, it'd hinder me in the long run. I wouldn't want to be a self centered snobbish smart mouth elitist. That's a lonely path, and only certain people can put up with that.
