I'm wondering. Were you (and the people who voted to delete the node in question) offended by that node or is it just that you think other people might be offended (or even damaged) by it? In other words, is it a case of offending your sensibilities or of "won't someone think of the children/my boss/my wife/the feds?"
As noted by someone else here, "fuck" might be one of the "most offensive words" in the English language, but that doesn't mean much. Words by themselves are one barely expressions, and context is everything. I have a hard time believing any single word is so offensive it should be banned here regardless of context. See also the various posts in this thread that use the word "fuck". I also note that the guidelines say "highly offensive posting", not any offensive posting.
In any case, we already have a system in place for censorship. It has been applied, and the node has been found "good enough" to keep. Appealing to the guidelines after the vote is probably not going to help. The consideration system is the usual mechanism to enforce the guidelines. That way the guidelines get interpreted by us monks on a per-node basis, which is a good thing, in my opinion.
