Here's the great irony for a family living in Oklahoma that would rather the Bible not be forced down their kids throat: Send them to a Catholic school.
16 years i spent in Catholic schools...from kindergarten through college graduation. I don't remember opening a bible....ever.....in class. Not once. I remember when we were young, like 1st - 4th grades, we had a religion class twice a week, and i remember the teacher reading some biblical passages and us discussing them. And once a week we all went to Catholic mass as a school.
But in math class, we learned math. In SCIENCE class, we learned science. Never once did we discuss creationism in biology class...not once...in 16 years. After 4th grade, i don't remember Bible discussions at all. Just mass, once a week, and students could opt out of that.
