“ One may protest against evil; it can be exposed and, if need be, prevented by use of force. … Against stupidity we are defenseless. … [R]easons fall on deaf ears; facts that contradict one's prejudgment simply need not be believed … and when facts are irrefutable they are just pushed aside ….” — Dietrich Bonhoeffer
