And kids aren't stupid.
The religious viewpoint of life's origins and fixity of species are taught within their church experiences. I don't ever remember a genetics lesson in Sunday school or a sermon on applying the "Rules of Hardy-Weiberg" in one's life. Shouldn't the "equal time" argument be used here ? Creationist ideas are religious, plain and simple.
Bring them into the public classroom and we'll head back down the road of reciting the Lord's Prayer ( which version ?) before math and fried fish sticks each Friday in the cafeteria.
An absurd extrapolation of their intent ? Not at all. Read the history of the creationist movement and learn what the likes of their leadership says when in the revival tents and behind the scenes with their believing bretheren. There IS NO TRUTH other than their own.
And if I might ask of our friends who want to see "both sides" presented, shall a biology teacher also be "highly qualified" with the required degrees and professional development credits each year, in his/her primary field AS WELL AS in the appropriate religious doctrines ?? And how many should that be ?
