One problem with these "debates" is that the evolutionists, of course, understand evolution, but the Creationidiots aren't talking about evolution at all, but about theories of the origin of life.
Evolution is simply how speciation occurs; over millions of years as species evolve. Says NOTHING about how life began. You can believe God, Allah, Zenu, space aliens, or L. Ron Hubbard in a previous life created life on Earth, and be an evolutionist.
Personally, I don't think discussing theories about the origin of life is necessary or all that valuable in High School, as there are a variety of (scientific, of course, not religious) ideas.
However, Evolution is SO basic to biology it HAS to be taught in high school.
Theories regarding the origin of life are no more important to understanding Biology at the High School level than the theories of the origin of water are to understanding Meteorology.
"Geez, reading this article, I have to point out yet again EVOLUTION HAS NOTHING TO DO WITH THE ORIGIN OF LIFE."
From the index of my kid's beautifully illustrated biology text ($90!):
UNIT 4: Evolution
Chapter 1: The Origin of Life
---maybe you should reconsider your statement that "evolutionists understand" that " Evolution has nothing to do with the origin of life."
