Let's be honest. Some have posted foul language on Free Republic. Usually, it's reported and the comment is removed. I've noticed similar incidents involving racist comments and "over the top" attacks on lefties.
Unfortunately, some lack self control and cannot express an idea (or cope with others disagreeing with their ideas) without cussing or partaking in other adolescent behavior.
However, we do ourselves no favors by denying its existence. All chsm-o-3 tried to do was to speak the truth.
To the poster who referenced DU's diatribes against Mr Cheney: do you want FR to behave like DU? I certainly don't.
My contention is that it is the exception not the rule as profanity as a rule is not tolerated by the owner of the site, however none of my posts said there is never any profanity uttered on FR, however I personally have seen little of the words that I consider profane during all of my postings to date.
