How do people swear in your state? Believe it or not, someone has made a study of this.
I have never been bothered by "those words" and I think the world is coming around to that point of view. Those who are bothered need to hang out with folks who use those words casually and to good effect in conversation.
But I will admit I do have one prejudice in this area. Whenever a man uses the word "bitch" to refer to a woman, unless it's clearly a joke, I always think that man has a problem with all women, not just with the one he's so labelling. For a long time, any male I heard refer to a female that way obviously was angry that she was not being subservient and less-than-equal the way he believed a female ought to be. I am willing to admit that there may be exceptions but every time I hear a guy say it, that's what I think. And it may still be valid in a majority of cases.
