Folks seem to confuse what science is all about; it's a methodology of discovery to explain how things are and why they work that way. Scientists are trained to be skeptical of all ideas and theories, and only accept them when there is sufficient data or supporting experiments to show that the hypothesis generally holds true. Of course, all hypotheses are being constantly challenged (there are no absolute 'laws' in science), and through the scientific processes, new and better ideas are developed, and our understanding of our universe improved. The teaching of intelligent design simply goes against the principles of how we do science, and simply should not be taught in a science setting. ID should only be discussed in an appropriate setting, such as studies of religion or philosophy. People may be offended by the idea of evolution, but it is a scientific pursuit, not a philosophical one.
