I am a Darwinist, but I do think both theories need be taught. Personally, I think creationism is just plain superstition and wrong, but because there are too many holes in the evolutionary process that we can't yet point to, we can't be 100% sure of anything.
I think all religion is superstition based and man made. I am agnostic by nature ... there IS a power greater than ourselves, but that power is unknowable by our tiny, limited minds. To interface with the power we have to "dumb it down" to simple superstition, using ritual, dogma and talismans to make use of "god" in our lives. BTW, I see nothing wrong with that.
I also see nothing wrong with people living true christian (as taught by Jesus) principles. Noteworthy was his rule about not casting first stones and loving one another. But I digress. I think religion has the capability to make better people out of some of us and, as such, has a place in education. But it need be done carefully. Creationism and Darwinism ought to be taught back to back. The theory of both principles should be available to developing minds.
I don't agree with prayer in school (or anywhere else we are forced to be) and would, if I had a child, give them the option to step outside during prayer if they chose. I, personally, have been at recovery meetings where the Lord's Prayer is said and rather than throw a pissy fit, I simply step back outside the circle and not take part. Freedom of religion is there for the taking here in Canada.
I was raised strict catholic. I joke about being a "recovering catholic" but in truth, I am grateful for the religious education I received (despite those annoying vestiges of guilt that pop up

). It gave me a basis for comparison once I was old enough to begin to choose my own path. In my young adulthood I realized the catholic church really had nothing to offer me and stepped away. I think any education is good, provided it is applied to minds old enough to question it. I believe in question everything.
Blind faith in either side of this question only serves to limit our already narrow ability to comprehend reality ... whatever that is.
