Ha ha. O well, I guess this is only an issue for gubmint schools, otherwise, would you be in favor of local school boards deciding what is taught without federal interference?
I've got no problem with private schools teaching ID.
I'd assume the parents would be aware of and approve of the curriculum ahead of time, and understand that some institutes of higher learning might have a requirement for evolutionary instruction as well, but that shouldn't be a problem for them. Either they could ensure their child receives both or they probably would want to choose a college that agreed with their beliefs and taught accordingly.
