The girl's statement that her school teaches the "theories" of both ID and evolution and therefore is less "narrow" is exactly the problem - ID is not a theory, it's a baseless conjecture without any evidence. A theory needs to be well-tested, with an overwhelming amount of physical evidence to support it, such that it is well-accepted by the scientific community. These students are clearly NOT being taught that crucial distinction, and therefore do NOT understand how science works.
