I wholeheartedly agree. However, from the standpoint of being able to argue that the "laws and principles" section is made up mostly of value statements and not scientific principles, it is an impenetrable argument. The teacher has no defense.
A liberal can argue anything.
He merely points out how intolerant and bigoted people like you are. Of course the publisher had to compromise in order to get his books in the hands of children over the heads of bigots. These poor kids could not be saved from their intolerant parents any other way.
I really admire you for standing up for your convictions but just a humble reminder that your precious little girl is at the center of this storm.
