Yes, that was a case of classic overkill.
Swearing doesn't offend me. I've done it myself, but, there is a time and a place for everything. Constant swearing is a sign of being, as I said, classless and having no self respect. Big deal, you know a dirty word, I am so impressed! We all learned them before middle school. Then we grew up! We thought enough of ourselves to use them when appropriate and use other real grown up words to express ourselves.
Constant swearing in public just makes a person look uneducated. It does serve to draw attention to oneself though and that might be the key reason.
Couldn't agree more. This is exactly what I was going to write. I'm not necessarily offended by swearing, per se, but I do think it is the product of a lazy mind. I have had conversations with my son in the past about when/where it is appropriate to swear, and sometimes in the car, if he's upset or angry about something, he'll ask if he can use a swear word. (He's 9.) I always tell him "no," that he is smart enough to think of another word, and he does.
I do think that as a society that is growing by leaps and bounds we do have an obligation to other members of society to practice good manners, as much as can be reasonably expected. We are not isolated any longer and it is important for people to learn to get along. An attitude of "I can do what I want, and if you don't like it, go away" is not conducive to a functioning society. Societal norms do change, like acceptance of tattoos, etc, but I think it is important for some things to remain outside of what is acceptable. A tattoo in and of itself is not offensive to me; a tattoo that depicts women (or men) in a disrespectful manner is. I would think this is common sense, but someone told me several years ago that common sense is no longer common, and I think that is true.

The remark about the point of swearing (repeatedly) being used to draw attention to yourself has merits as well. I'm constantly reminded when I go out in public of the song "Loud" from the play Matilda. It is spot on the way most people act.
