Dietrich Bonhoeffer's theory of stupidity

I've been getting into learning about Dietrich Bonhoeffer recently, which has been really interesting! His theory of stupidity is especially interesting and relevant to the present.

"Stupidity is a more dangerous enemy of the good than malice. One may protest against evil;
it can be exposed and, if need be, prevented by use of force. Evil always carries within itself
the germ of its own subversion in that it leaves behind in human beings at least a sense of
unease. Against stupidity we are defenseless. Neither protests nor the use of force accomplish
anything here; reasons fall on deaf ears; facts that contradict one’s prejudgment simply need
not be believed — in such moments the stupid person even becomes critical — and when facts
are irrefutable they are just pushed aside as inconsequential, as incidental. In all this the
stupid person, in contrast to the malicious one, is utterly self-satisfied and, being easily
irritated, becomes dangerous by going on the attack. For that reason, greater caution is called
for than with a malicious one. Never again will we try to persuade the stupid person with
reasons, for it is senseless and dangerous."
