IMHO, in the context of the discussion at hand, it tells us that belief in creationism, in and of itself, cannot be held to be a moral indicator.
Precisely, which is why I'm in agreement with others that such a comparison between Christians and Muslims, absent a moral equivalence, is irrelevant and meaningless.
I'll it up to the the readers, then, to decide for themselves what the motive is for proposing such a comparison.
