I concur with Jack that most ethical disputes are about facts, and if not then about relative weights for values. Freedom verses existence, etc.
What I would call a real difference in ethics would be the introduction of a completely novel terminal value (which I can hardly imagine) or differences in abstract positions such as whether it is OK to locally compromise on ethics if it results in more global good (i.e., if the ends justify the means), etc.
