I will answer. It is Westerners. But they have made very serious mistakes about islam, believing them to be basically peaceful, which has turned out to be dead wrong. The biggest mistake of Westerners has been to learn nothing from islam's merciless, sanguinary history. And I will say that just because islam worships something that does not make them a true religion. They are in fact the antithesis of real religion, which is helping the widows, loving your neighbor, helping the poor, spreading your faith through education and example, NOT by the sword. Islam is evil to the core, and evil is not the definition of 'religion', it is the opposite of religion.
Though I am reminded that great thinkers of the 20th century like Winston Churchill and Hilaire Belloc had both written dire warnings about islam rising again and threatening the West. Unfortunately the liberal/ socialist dupes who infected Europe and the U.S. have been blinded to reality by their unbelievable pomposity and hatred for truth. In other words, the rise of Islam in the West is directly related to the self-inflicted wounding and crippling of Christianity. The modern West has been unable to see the evil of islam because we have not been looking at it through the eyes of faith.
The bloody mohammedans didn't have to conquer us, we have been conquering ourselves by replacing Christ with humanism and science. Meanwhile the enemy has stood by watching like wolves licking their chops. It is no coincidence that the West is under islamofacist attack at a time when Christianity is staggering around in its all time weakest state of faith.
Thank you, Crusader, although I wonder if our "friend" is even capable of understanding.
