I can understand being slightly upset about this, but trying to hang a teacher for this reason is -- IMO -- stupidity. Teachers make mistakes, if you call this a mistake or not. Kids shouldn't be forever traumatized over this and if they are they're probably too sensitive to begin with. If a parent so chooses to tell their children about Santa those parents can come up with an equally "inventive" reason why their teacher doesn't beleive in Santa. Good grief.
