I think that all teachers do not refrain from giving opinion as fact. It is the best teacher who allows for students to have their belief without question. Education presents multiple sides of an argument. Such as with the aforementioned abortion. It is not normal but it is allowable by federal law. Abortion is considered through a thoughtful process between a woman and her doctor and whomever else she thinks to consult, her husband or religious leader. It is not normal just legal for now.
Many other religious believers have issue with the act of abortion, not the law…
Education stretches the mind, helps to see there are more than one option and if someone calls that brainwashing, then they are not getting different perspectives, just one RIGHT one.. The one of the person, institution or belief.
