Very well. My only point about the ancient Greeks (specifically, those who believed) was that today, in 2010, I don't think most of us would have too much difficulty dismissing a genuine belief that Zeus took the form of a swan as nonsense. Certainly, if someone wanted to pass laws to appease or flatter Zeus we'd oppose that, yes? And if someone were to suggest that belief in Zeus is good, because lots of good people have believed in Zeus, and have done good things while believing in Zeus, we'd probably shake our heads. And if someone were to insist that a disbelief in Zeus is a form of faith that's really no different from a belief in Zeus, I think we'd probably tell them to take a long walk off a short dock.
So why, specifically, is the belief that God spoke to Moses as a shrub on fire different? Why does that retain a veneer of maturity and rationality that a belief in Zeus would not?
