Well, how about the world of Martin Luther? He was the founder of protestantism, and all christianity outside the Catholic and Orthodox churches trace their roots back to Luther.<quoted text>Only in your narrow little world.
Here's just a sample of Martin Luther's thinking on the relationship between reason and faith:
"Reason is the greatest enemy that faith has; it never comes to the aid of spiritual things, but -- more frequently than not -- struggles against the divine Word, treating with contempt all that emanates from God."
"Reason must be deluded, blinded, and destroyed. Faith must trample underfoot all reason, sense, and understanding, and whatever it sees must be put out of sight and ... know nothing but the word of God."
"There is on earth among all dangers no more dangerous thing than a richly endowed and adroit reason... Reason must be deluded, blinded, and destroyed."
Martin Luther, quoted by Walter Kaufmann, The Faith of a Heretic,(Garden City, NY, Doubleday, 1963), p. 75
"Reason should be destroyed in all Christians."
"Whoever wants to be a Christian should tear the eyes out of his Reason."
"To be a Christian, you must "pluck out the eye of reason."
So it isn't just an atheist thing - christians also believe one must choose between using your critical thinking and having faith. Choosing both is not an option. So says the founder of your religion.
