For example, the very word 'islam' was not revealed from heaven or invented by Muhammad. It is an Arabic word which originally referred to an attribute of manliness and described someone who was heroic and brave in battle. But when you turn to ecstatic, confused speeches of Muhammad as found in the Qur'an, you do not find anything outstanding. There is nothing which matches the beauty, substance, or style of the way Jesus preached the gospel during His lifetime. Darkness is the absence of light.
Ignorance is the absence of knowledge.
Ignorance is the mother of prejudice. With the exception of a few liars and demagogues, people in the West have good nature and are attracted to the truth and decency. Since the time of the Crusades, the West has been receiving small or big doses of poison against Islam and Muslims. While there were no Muslims or a very insignificant minority of Muslims were living in the West nothing could be done to bring the light of Islam in wide wilderness of darkness about the knowledge of Islam. Now, there is no excuse as the Muslims are living as significant minorities in North America and Europe.
