You cannot be serious. This comment and those of the others are simply ludicrous.
As a Christian, I must say that the only thing more disgraceful than our Church's behaviour during the Dark Ages is modern attempts to deny or justify them. (Protestants burned "witches, Catholics burned "heretics" - neither group are blameless.) Let's just admit it, repent, and go on.
Schmelvin and Stryker are right. Go learn your history. It is embarrassing to be so wrong, and gives fuel to those who would ridicule us.
By the way, in no way does this mitigate the continuous, habitual, and I believe worse, offenses of the Muslims now or in the past.
What is so ludicrous about keeping a product of immense value and immense labor under secure protection? Surely you are aware that medieval copyists did everything by hand, and that there was a market for Bibles just as there was a market for Relics(despite the Ecclesial prohibition on the sale thereof). If there was only one copy of the Bible within twenty miles, and opportunistic thieves about, why not have security?
What is truly ludicrous is to judge events of the past as if they happened yesterday in Fresno. If you have no concept of the cultural context in which these things happened, then you will stay in a state of perpetual shock, as you seem to be.
