@Ragman,
I could be wrong but I think I'm aware of the post you've referenced and I believe if you reread it, you'll realize that the poster was being facetious. I don't believe he meant that Zionists were equal to "kikes," but that the term "Zionist" was a substitute, for some people, for the term "kike." In other words, anti-Zionists are thinly disguised anti-Semites. Whether or not anyone ascribes to such an opinion of anti-Zionists is immaterial for this discussion.
I raise this not simply as what I believe to be a correction of your misunderstanding, but to provide a good example, IMO, of the difficulties with specific word filters, zero-tolerance for the use of certain terms, and censorship in general. (Not that such mechanisms have been discussed by Robert as part of the new A2K)
Several years ago I wrote an e-mail at work that included a sentence that read something like "I believe we will find that if we decide not to compromise on this request, it will queer the deal." The e-mail was about a page in length and so the sentence wouldn't have necessarily stood out.
After I sent it, I got a Non-delivery message that simply advised me it couldn't be delivered to it's intended recipient. To make a long story short after re-sending it several times and exhausting the few remedies I thought might work, I spoke to someone in IT. Eventually he asked me if it was possible that I had used a term that the systems "profanity filter" might block. Obviously, the offending word was "queer." Once replaced with a synonym, the e-mail was delivered.
The point, of course, is that my use of the term had absolutely nothing to do with anyone's sexual orientation, and was entirely innocuous. In retrospect, I suppose I could have anticipated a problem using the word, but first of all I wasn't aware that a "profanity filter" was being utilized and, secondly, given the context in which I was using it, it didn't even occur to me that someone (including a censor) would misinterpret my usage. Frankly, if I had paused to consider it's use I would have went with it not only because it was perfectly acceptable in the context of the e-mail, but because zero-tolerance policies annoy me. (I am reminded of the Washington DC official who got in hot water for using "niggardly" in a speech despite the fact that his usage was totally appropriate and entirely innocent of malice)
In the case of the post to which I believe you refer, the word "kike" was used. I think we would probably agree that "kike" is akin to "fag" in terms of being a slur that paints a wider group that any individual addressed and so if the poster wrote something like "Shut the hell up you kike!" and a moderator became aware of it, he probably would have (or should have) suffered a suspension; based on the logic behind the hawkeye case.
Now if I am right in my interpretation of the poster's usage then not only was he not using "kike" in a mean-spirited and derogatory manner, he was, if not defending Jews and/or Zionism, at least making a negative statement about anti-Semitism.
I presume that if you had reported the post and the moderator agreed with your interpretation so that a suspension was seriously considered, the poster, would have, at least, been advised of the alleged offense and been given a chance to explain his actual intention.
At least I hope so. I once had a comment rejected at the Comments section of a major newspaper's online site. I wasn't notified in anyway as to why or even that it had been rejected. I did notice that it didn't show up and so after a period of time wrote to the paper asking them for an explanation. They provided one and it was clear they had misinterpreted what I wrote. I disabused them of their misunderstanding and they apologized and allowed it to appear on their site. I'm fairly sure it was an innocent mistake by someone that has to make a lot of rapid decisions on the fly about posts. Some of the articles generate fast and furious commentary. No real harm, no foul, but it does point out that words can be misinterpreted.
I think we all need to be prepared to re-examine whatever posts we immediately find offensive, not simply to prevent unnecessary reporting of posts to moderators, but to prevent unnecessary turmoil in our discussions. I would venture to say that almost all of us, at one time or another, have had our comments misinterpreted here. That it's often by someone who, for whatever reason, has an ax to grind going in may be a coincidence, but I doubt it.
(Of course if we are each referring to two entirely different posts...
