I was really referring to swearing in the religious sense. I work for the Salvation Army (ironic no doubt) and my coworker/supervisor who is an evangelical (perhaps the most open-minded, non-judgmental, sincere, and humble Christians I have ever known) is offended when residents in our homeless shelter curse using "Jesus Christ" or "god damn" this or that. He doesn't like the F-bomb or other swearing either, but is particularly offended by the religious curses and I can appreciate that.
It has been my observation that many people curse or swear without even being aware of what they are saying or how often they are saying it. Others who seldom swear get a lot of attention when they do because those who know them realize it is serious, or that they are particularly upset. I admit that by myself I swear frequently, but not around others and obviously not at work (my coworker has said he has never even heard me cuss at all).
I wondered, though, about people who swear using "Jesus", or "Christ", or "god damn" and they are not religious and so those particular words should not have a strong meaning to them, but would culturally here in the West. But would someone in another culture whose god is named "Ralph Malph" be prone to swearing by exclaiming "Ralph" or "Ralph fucking Malph" or "Ralph damn it"?
Why would myself, an atheist, find that using the name of a religious figure such as Jesus would have meaning as a curse word by myself? Or is it a learned cultural behavior regardless of religious belief or non-belief? Do other cultures have similar swearing behaviors?
