Very good point. I strongly support this decision, and think it was the right one. However, the people who oppose it should be very careful about what they ask for. If this had been allowed, every religion would have asked that their theory on the origin of life be taught, from Hinduism to Flying Spaghetti Monster-ism.
I include the latter, because it would happen, and it would then put the courts in the untenable position of deciding which religious beliefs could be taught in the schools. It would be used to marginalize Christianity, and ultimately polarize Christians against non-Christians, and there are more on the non side in the US than most of us imagine.
Consider the scenario of muslims moving to a town of about 15,000 in numbers large enough to control the vote. Probably only take 5 or 6 thousand the first election, and they control the city government and school board. You wouldn't want them to schedule school holidays around Ramadan or the birth of Mohammad, or require the girls to wear veils to school would you? It's easy to say it doesn't matter and that a little won't hurt when Christianity is the dominant religion, but if that changes, we would see things from a much different perspective.
ANd so, what if the judge is a Muslim who wants to spread his religion? The problem is this works both ways. I would rather see the people making the decision, not one man. (and it sounds as if the people would have made the same decision the judge did in this case).
When we get to the point where one group has enough numbers to play our your scenario, it hardly matters anymore, it's going to happen.
