NPOV is a technique to cope with intractable disputes, not some kind of weirdo Wikipedian-only quasi-religion. :-)
No, NPOV applies whether or not something is disputed. People have argued about what NPOV is meant to accomplish, but it most definitely applies to _every single thing_ in the article namespaces.
So while you may be hard-pressed to find somebody who says that the death of 300 innocent people from a bridge crashing is not unfortunate, we don't say "Unfortunately" or "Tragic event" or "unfortunate event" or "tragedy" because that is passing judgement and, more importantly, it is not NPOV.
Ultimately there is always somebody who argues "Well, since nobody actually disagrees with it, it isn't POV". The response to that is: "I disagree with it strongly". Then the other party will most likely take one of two actions, saying "OK, you're right, it's POV" or they will go on to throw insults and profanity at you for having a viewpoint (for example, if I say "I strongly disagree with the assertion that murder is wrong", the other party involved might say "What kind of crazy idiot are you?").
However NPOV policy doesn't apply to the whole world (although if you're a Wikipediholic, you may have had the experience of hearing somebody say something POV in real life and wanting to click the "edit" button). It may or may not apply outside of the article namespace. Some people say it doesn't apply to the mainpage, some people say it doesn't apply to Wikipedia: pages, some people say it *does* apply to User: pages, although nobody argues it applies to talkpages (after all, that's what talkpages are for, aren't they? expression of an individual's POV?). There are differing viewpoints - I for one believe it applies to everything on every Wikipedia, including the interface, with the exception of talkpages, userpages, and other pages specifically intended to be safe harbors for POV on Wikipedia (for example, on WP:RfA, I can say "____ isn't a good editor" even though it isn't a talkpage or a userpage, nobody would disagree with that most likely), but it seems to me the majority opinion is that it only really applies to articles and article titles, and thus it's OK to put on our logo "I don't care what your mama says, Christmas is number o-one, I don't care what your papa says, Christmas is really fu-un" or write in a UI message "If you don't click 'ok', you are an idiot and must not be my religion". But those are extreme cases not likely to happen, so really they don't work well.
