I think there may be two schools of thought here, though.

Some people interpret the very act of cursing as incivility, regardless of the purpose, and some people only view it as uncivil if it is meant to be uncivil.

Personally, I don’t agree that the only reason to curse is to offend. In my mind, curse words have a very specific meaning and sometimes they are by far the most appropriate word for a situation.

I would liken it to using words that describe parts of the human anatomy. There are some people who would never say the word penis in polite company, but sometimes it’s just the only word for the job.

Also, I’m not suggesting that my interpretation is the only reasonable one, just that I think there are widely varying positions.
