I've heard this claim a lot, but it appears to be a false claim. The theory of evolution assumes that life originated from "natural processes," and continued to evolve from that "natural" start. If the theory did not make such an assumption, then evolutionary theorists would not be so dead-set against the possibility of intelligent intervention within the evolutionary flow.
and their woeful lack of understanding of basic scientific terminology.
Lamentably true in some cases. However, it is also true that those on the "evolution" side of the fence tend to be ignorant of their own assumptions, and the weaknesses thereof. Same crime, albeit with different symptoms.
They don't want to learn. They already "know" what is true, and little things like "reality" aren't going to stop them.
A rather broad brush condemnation, don't you think? And it is clearly true that willful ignorance of "reality" is not limited to those on the "ID" side of the fence.
