I'm with you on your entire comment - except for the 'arguably' part (so I gave you a helping hand)...
2 Corinthians 4
3 But if our gospel be hid, it is hid to them that are lost:
4 In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
The god of this world (satan) entraps many of our friends and brethren and turns them into 'enemies' (causing us to forget that our real battle isn't against people we disagree with - but against 'principalities and powers').
Prayers that these people are able to shed the chains of darkness...
On Islam:
Real Prophets climb mountains to be closer to God.
They don't crawl into caves to listen to the hissings of The Serpent.
