When faith displaces intellectual rigor, "the faithful" believe it their duty to champion intellectual blindness and deliberately impugn any reasonable, rational finding that contradicts their faith. When faith is considered the most important divine directive, it is not only acceptable to trash scientific findings that threaten the faith of true believers: it is necessary to trash them. (See "sola fide" - http://en.wikipedia.org/wiki/Sola_fide) Fidelity to preconceived beliefs (regardless the measured conclusions of reason, logic and Love itself) is the summum bonum for anyone whose faith is everything. The prime directive of "true believers" is to represent fact-as-fiction while confecting de novo fictions to bolster faith. Lacking formation in intellectual integrity, "the intellectually stunted" must preserve blind faith by the deliberate degradation (and ardently desired destruction) of Truth. Alongside St. Paul, blindly faithful Christians argue that the world's wisdom is foolishness and thus exempt themselves from any rational challenge even when rationality and The Law of Love are co-terminous, even when irrationality rejects The Law of Love.
The greatest threat to the human psyche is dissolution of identity so that those who identify themselves with rigid beliefs, must - above all -- preserve those rigid beliefs so that they not shatter or crack.
In the 13th century, Thomas Aquinas "threw a life-vest to humanity" when he described the proper relationship between faith and reason:
"Arguing against those who said that natural philosophy was contrary to the Christian faith, (Aquinas) writes in his treatise "Faith, Reason and Theology that "even though the natural light of the human mind is inadequate to make known what is revealed by faith, nevertheless what is divinely taught to us by faith cannot be contrary to what we are endowed with by nature. One or the other would have to be false, and since we have both of them from God, he would be the cause of our error, which is impossible."

Except for those who cultivate high order thinking skills, humankind is experiencing a groundswell of Aggressive Ignorance based on whole-cloth falsehood.
At ground zero in America's culture war, we are living through "The Death of Epistemology"
In effect, broad swathes of humankind - often seeing themselves as ordained agents of God -are reverting to The Sea of Superstition that has been humankind's enduring milieu.
Eric Hoffer's "The True Believer" (1951) is the best available exploration of blind faith as human debacle. http://en.wikiquote.org/wiki/Eric_Hoffer
