I always found this a trite line (among many) in the film. So, Obi Wan, *only* the Sith deal in absolutes? So I guess that makes you a Sith then, eh?

There are definite problems with a completely black and white mindset, a completely us vs them mindset, but there are useful benefits of it as well. The trick is to be flexible and adaptable, while at the same time sure enough to take action on what you justifiably believe.

If it walks like a duck and talks like a duck, it's probably worthwhile to assume it's a duck, until further evidence comes along that it's really an animatronic display.

Someone who does not hold a belief in any gods is an atheist, according to the simplest definition of atheist. This is pretty black and white. You're either a theist (belief) or not (no belief). According to that definition, there is no in between. So it is fair for you to internally distinguish people by this criterion. However, the flexibility comes in with the consideration that people don't like to be called atheists because a) atheists tend to get shit on, and b) they have a different concept of what atheist means. So just cuz someone's an atheist by the lacking-belief criterion, doesn't mean you should insist that they call themselves atheists JUST for that reason. There are better, more pragmatic reasons why they should call themselves atheists, namely for the same reasons this website exists. So if it really irks you that they don't admit their non-belief, then talk to them about why non-believers should stand up and be counted. But be flexible as well, because the world is more complicated than just word definitions.
