Even at good schools with non-religious teachers, students are undoubtedly taught lots of information that's false. Teachers are of merely average intelligence and often just don't know that what they're teaching is false.

Which is fine because if the subject matter actually matters, there will be ample chances to relearn it later. Having teachers teach stuff that is wrong is only a big problem if you think teachers need to be infallible. But the fact that teachers can be wrong seems to me one of the more important true things kids learn in school.
