After following the link to an AP story, it seemed local coverage would be
more helpful.  So, I checked out the DailyFreePress.  Interesting that a
story earlier this year was about "swearing being a healthy stress outlet".
Now it is banned.  Also, lots of letters in recent issues.  The local story
at the link that will likely need to be copied and pasted due to its length

Experts say swearing may be healthy stress outlet
By David Brand
Dropping the "f-bomb" today will not necessarily get your mouth washed out
with soap-in fact, it might be a good thing, according to Boston University
faculty and students. A recent survey conducted by the Associated Press and
Ipsos Public Affairs found that 42 percent of Americans frequently hear
profanity in public, while just 8 percent of those polled said they never
come across swear words.
