No....Intelligent design is not a good idea, It' neither fully grounded in religion nor science.....
Religion is a belief, science is a fact.....
No one can take away my beliefs by teaching me science. Some of our most bright and talented scientists are extremely devout.
Theology belongs in the Home and Church. Our schools should continue to try to teach the best science available.
If you're so worried about everyones' soul, try the Catholic Church. Catholic Schools have taught Evolution for years with little angst. The church does not take a hard literal only translation of the bible.
"Religion is a belief, science is a fact"
Science is based on some facts, but also theories that have not always proven to be factual. Example, the theory of evolution, and it's multitude of missing links.
