To dip a bit into my real feelings here, I believe in an absolute morality...that right and wrong exist....but I also believe the world is messy and it's REALLY hard to see what is right and what is wrong with certainty all the time. There are LOTS of variables in life and an action that is the right action in situation A could be the wrong action in situation B. That's where the shades of grey lie, not in the idea that morality is relative, but in the idea that is really hard to be certain what is right and what is wrong in a situation combined with the fact that holding to convictions in a meaningful way is a hard thing to do. We're prone to get tangled up into the wording and language of our convictions because that's easier to do than to analyze each event and consider what the true spirit of your convictions demands.
