Let's just say that the result these arbiters of text book content wish for as a conservative Christian nation that is opposed to taxes and elects Republicans to office every time. If they can get the content in text books to reflect their wishes, there are a lot of students who won't have teachers who present opposing views, and this will be accepted as "fact." If you can set the ideas early, you do a lot toward achieving your goals. I'd be willing to bet there is no critical thinking component, or it is severely dumbed down, in these text books.
