I use quite a few of those words...
but, as someone has said earlier, the use of profanity simply shows ignorance on the part of the user.....I have to point at myself as well.
There is no right way to use them...its simply a bad habit, and hopefully one that children will not learn.
Will they hear and learn the words...sure..............will they use them, that is where the choice comes in.
I have to say that growing up, profanity was never used in my family, among my friends, etc....and therefore I didn't use profanity. BUT, when I began working, and my friends changed....unfortunately my language did as well. It is a habit I'm trying to break, and I would hope that children don't learn the habit.
I have a better grasp of the English language, and I would hope that people know me for that, rather than the fact that I drop the "f bomb" a lot....
