Fisrt I did not listen to the video, my computer is messed up right now. I can not coment on that in particular.
Yes creationism should be an option to teach, but on a county by county decision. Schools are for learning about important beliefs that shaped the world. This is a big one among others. Interestingly, our school did teach about Islam beliefs ( and that it was the religion of the majority of people on earth) , and the flat earth belief, etc, as well, and evolution. This was in a public school in the mid 70's in the bible belt of the USA
Government should NOT be dictating one over the other in our schools. But in the same token, if one school decides to teach it and another not, that should be the decision of the school, or county etc, (voters) not by an overall government decision. At that point it is a decision of the comnmunity.
Choices is what America was founded on, not dictatorship over beliefs.
