It is not the first time we've seen that argument, and it won't be the last. It appears at least once a month I reckon, and usually attracts applause from others on the creationist side. I've never yet seen that argument flamed by a creationist (but in general creationists appear to be very careful not to flame the obviously flawed arguments of other creationists; it's like any lie is good enough, if it rejects evolution.)
That's very similar to how the left operates. They refuse to flame the real whackos on their side, like Cindy Sheehan when she says stuff like the foriegn fighters in Iraq are "freedom fighters". They just ignore it, because the whacko is on their side.
