EY has publicly posted material that is intended to provoke thought on the possibility of legalizing rape (which is considered a form of violence). If he believed that there was positive utility in considering such questions before, then he must consider them to have some positive utility now, and determining whether the negative utility outweighs that is always a difficult question. This is why I will be opposed to any sort of zero tolerance policy in which the things to be censored is not well-defined a definite impediment to balanced and rationally-considered discussion. It's clear to me that speaking about violence against a particular person or persons is far more likely to have negative consequences on balance, but discussion of the commission of crimes in general seems like something that should be weighed on a case-by-case basis.

In general, I prefer my moderators to have a fuzzy set of broad guidelines about what should be censored in which not deleting is the default position, and they actually have to decide that it is definitely bad before they take the delete action. The guidelines can be used to raise posts to the level of this consideration and influence their judgment on this decision, but they should never be able to say "the rules say this type of thing should be deleted!"
