Soapboxing aside, I'd say the OP's article is correct. Religious indoctrination has no place in school.
Religion should be kept out of the public schools. In most cases, once a child is old enough, they will choose whether to accept the science or the religion based version of where we came from.
Nothing wrong with religion in schools. Actually, I think it's very important to learn about religions. ALL religions. Education, not indoctrination. Otherwise you get homeschooled regarding religion, and that's mostly a bad thing, because there you have your indoctrination then.
Non-education on a topic is never the right answer.
