Can Mormons see Grey? Dealing with Difference Part II

Roughly speaking we can talk of two different ways of conceptualizing a world imbued with morality—as black-and-white or as shades of grey. In regards to our religion, I see faithful members of the Church in both camps. Those that see in black-and-white, view the Spirit as a power that is either present, or is not. Any given thing is either of God or of the devil. A church is either the church of the Lamb or the church of the devil (1Ne. 14:10). Those that see in grey emphasize parts of the gospel that talk about the good in all things—growth line upon line, and improvement grace by grace. And sometimes of course we fluctuate back and forth between these positions.

To give a more practical example:
The black-and-whites would say that one scene in a movie (be it sexually explicit, violent, or otherwise) warrants not seeing the movie altogether. The greys on the other hand, would say that the one scene, while not good, does not ruin the other enlightening parts of it.

The questions that I’m interested in are as follows:

Is it really the case that Mormonism allows for two different world views? If so, then how should the black-and-whites relate to the greys? Is there something else that holds us together as Mormons besides a common world view (or other parts of a world view larger than what I’ve described)?

Is there a progression involved? In other words, have those that see in grey “evolved” beyond seeing in black-and-white? Or have they simply made a choice to use a different lens with which to view the world—a different, yet equally valid lens?

I certainly have a lot to say, but I’d like to know that there are others out there who are interested in discussing the issue. So please provide some of your preliminary thoughts.
