I agree that this question should not have been permitted to make it this far. It's an interesting question, but really doens't have anything to do with history per se. Having said that, some of the answers do indicate a hsitorical perspective on why this situation exists.
I have mentioned this before and will mention it again. Because the site is still in beta mode, we are more likely to accept borderline questions in an effort to encourage participation. At some point we will have to go through every single question on this site and start cleaning them up, which means removing questions like this.
Until then, we are going to allow the community to decide what their tolerance level is. If enough people vote to close it, then it will be closed. Another more likely option would be for people to flag it and suggest that it be converted to a community wiki. Because of the amount of votes on both the question and the answers, it is obvious there is some interest in the topic. However, it would probably be more appropriate as a wiki topic.
Having said that, we as moderators prefer not to overextend our authority. The moderators we have on this site have each taken the position that we would prefer to have the community decide what stays and what goes. If there is something that is blatantly inappropriate we will act on it. Otherwise, we follow the guidance of the community.
