I think we all can agree that there should be a separation of church and state. Where we might have a divergence of opinion is in someone – including the state – telling me what I can or cannot teach my child.
The community, via the state, can tell me that my child must learn about evolution in school. It cannot tell me what I can and cannot teach him in the privacy of our home or in the confines of our house of worship. While I am not a constitutional lawyer, it seems reasonable to me that trying to enforce such a restriction would be an outright violation of the Free Exercise clause of the First Amendment.
For the record, some of the best discussions we have in our house are about the apparent contradictions between Darwin’s Theory of Evolution and the common English translations of Genesis, and how Jewish scholars (starting with Maimonedes) reconcile the two. But that’s another topic.
