Keep in mind that there's a well-argued view that the worst excess of enlightenment thinking is totalitarianism, and that the American Revolution was in part a Counter-Enlightenment revolution.

Of course there is no one "Enlightenment" to point at - but the point is that one can take reason too far, to the point it has the same effect as religious extremism: "you are logically wrong so I'll hurt you".

Ultimately the point of many religious faith is a constant reminder we are all fallible and do not have access to absolute truth. Many fundamentalists forget this, preferring to focus on morality over faith.
