One point that I don't believe has been made; there is some precedent for treating articles of an iconic nature differently to other articles; for example the MOS more or less mandates that we should emphasise national varieties of English for subjects that are iconic for a particular nationality; we treat these in the context of the nation that originated them.
While that doesn't speak to articles iconic to a particular *religion*, it doesn't seem completely unreasonable that some extension to the guidelines could potentially be made for these kinds of cases where edit warring, at the very least, is rather likely.
The question would be what kind of guidelines could be drawn up; perhaps if the guidelines were such that:
a) material offensive to significant number of proponents associated with that religion was moved to a different article
b) clearly labelled wikiinks were present that pointed to the moved material
If wikilinks are present, then I don't see any reason for javascript mechanisms, and we would not be censoring ourselves, the material would still be present in the wikipedia, and in clickable form.
