Good.
Why should the Darwinsim be taught as truth?
It shouldn't because science doesn't deal with "truth." It should be taught as the current state of scientific knowledge on the subject, as all science should be. One day maybe another scientific theory will come along and supplant evolution, but until then evolution is what should be taught in science courses.
Because it makes more sense than "magic".
Hey.. how old do you suppose the world is?
