The thing is, the idea that anti-evolutionary theory is claimed to be unfalsifiable and therefore not science, which is simply not true. Evolution opponents often believe the Bible is infallible, but they do not hold the scientific evidence they present to be unfalsifiable.
Step 1: Behe claims the flagella is irreducibly complex; i.e. could not possibly have evolved.
Step 2: Evolutionary biologists explain how the flagella could have evolved.
Step 3: ID polemicists complain that the evolutionists haven't provided a detailed, step-by-step accounting for how the flagella actually evolved, calling the evolutionary explanation a "just-so story", a "promissory note for an explanation", etc.
If ID is falsifiable like you claim, then you should be able to tell us precisely what kind of evidence would convince you that ID is, in fact, false.
You assume I believe in ID. I already stated I don't think ID is a good theory. Just saying that organisms are too complex to have evolved is not a good argument.
