If one examined medevial Europe's history, and the teachings it perpertrated on its peoples, it will be found to have direct allignments with Nazism. The writings of Luther, for example, are very similar to Hitler's Mein Kampf, with almost direct lift-off verses.
However there is little or no truth that the Europeans did not know wht was occuring under nazism. In many states the people assisted the Nazis in masscreing its Jewish populations, especially in Poland, where the first camp was established, with its christian population actively pointing out their Jewish neighbours to the Germans. Considering that European christians had a continious and old history of acting according to the teachings of the church - the 'Ve vere not avare' claim is very weak. Although there were some brave christians durring the Nazi period, who risked and lost their lives defending the Jews - critical mass applies, and the majority were already beyond changing their minds after centuries of racist teachings.
It is a pity that an otherwise brilliant nation like Germany seccumbed to racism, fostered originally and for some 2000 years in so-called emancipated Europe - which was hijacked by the church. During the dark ages, European christianity under church rule was the biggest mass murderer of innocent peoples in all past recorded history, with its charges of deicide, blood libels, the Protocols and other such horrific falsehoods; the crusades, instigated by the church, was only one of these results - but far worse occured inside Europe.
Today, Europe is silent of radical islamists emulating these doctrines, and openly teaching these European falsehoods as real history. There is a full onus on christians to address these falsehoods, because they came from Europe. There is a greater onus on Muslims to address such false and horrible doctrines - it is simply not credible they believe such to be sanctioned by a Godly inclined religion.
The correction of these attrocities will benefit Christianity and Islam - and its failure will eventually negate these religions. Truth does not get destroyed, it eventually pops up by itself. Truth is a correction, and the universe is omherently built on truths, which is referred to as correct equations in science and maths. It has become very difficult for christians and muslims to correct these false and racist teachings, because of fear and/or cowardice, and partly because some mistakingly believe them as truths and by alligning such terrible doctrines as being of divine origins.
We can see that today, a mass murderous Pope called Pious is to be made a Saint, and as yet there is no fatwah for Bin Laden. What does that say - are all the people free of onus and guilt here that they remain silent of it? It is this very silence which was and is today the cause of all such attrocities. There is only one applicable divine law, or moral truth, which applies:
'A FALSEHOOD AND THE HOLY ONE CANNOT ABIDE TOGETHER'
'YOU SHALL NOT WITNESS YOUR FELLOWMAN'S INNOCENT BLOOD AND REMAIN IDLE'
- This means a religion based on promoting a lie and using it to commit evil - whereby all its adherents remain silent - will definitely be destroyed. This is what occured with Sodom, Ghammorah, and later with Ancient Egypt, Babylon and Mighty Rome.
