I didn't think it was a big deal until I spent significant time around swearers and non-swearers. There is just an ugliness in swearing both in the harsh consonants that intrinsically reflect the ugliness of the words and the general attitudes surrounding the spewing of the words. I remember a non-swearer who shared with me the misperception she often felt was falsely accused on her. This surrounded her use of other words to express frustration or pain or anger or what have you that the underlying emotions of those softer words were curse oriented, just sugar coated or something to that extent. She told me that was a perennial confusion with her, that it just was not the case, her emotions did not reflect the harsh swearing attitudes/content. Pretty interesting thought, I used to think that internally they had all the rage/etc but just repressed it or whatever. I learned apparently cursing does reflect an internal state of one's heart that could very much be lacking entirely in others.
