You can have your own opinions, but not your own facts. I believe it is a fact that Islam and Christianity share much in morals, stories, rules and so on.
But those are merely the externals . What are the similarities in the core , the essence of religion ? If they're so similar , why have they been at loggerheads for so long , whereas India and China , both of who share similar religions , never had a religious war ( only once did some Muslim occupier of India once tried to invade China ( he is known to have been slightly off his rocker ) - and watched his entire army perish in the Himalayas

) ? It's because at the core , Islam and Christianity hold different values to be dear , but Hinduism and the Chinese religion share many fundamentals , and , most importantly , are not exclusive . They do not claim that theirs is the only way . These religions are not totalitarian .
Christianity , after reforming itself , has lost its totalitarian bent . The Church no longer aspires to completely control every aspect of a believer's life . But Islam hasn't lost that bent yet . Anybody who reads the compilations of fatwas on this topic will realist that the common people are urged to approach religious authorities even for the resolution of secular issues ( such as - when and how to plant crops , whether or not a well into which a frog has fallen and died is impure , whether on not a vessel licked by a dog or a cat is impure , and many other completely secular things which have no bearing on religion at all ) will realise this , because Islam does not distinguish between the divine and the secular . There is no "Render unto Caesar" in Islam - everything is only to and for God . No distinction between Ulema and State - let us remember that Mohammed's greatest achievement was forging a strong , centralised state out of what were essentially desert nomadic tribes . His medium for doing this was his religion . And that statist flavour has pervaded that religion ever since . There is no way that they can ever be separated , unless there is a great cultural shift in the Muslim regions - a cultural shift which is , alas , rendered impossible by the nature of the religion itself

.
An interesting by-product of this was that wherever Islam went , it carried its culture with it , and it seeks to turn
every place it spreads to into its own little version of 7th century Arabia . Indonesia is a textbook example of the impact of different types of religions on people and their culture .
Hinduism spread there by three means - Indian settlements ( which include the trade effect ) , royal patronage , and Indian conquest .
One of the most interesting things about the spread was that it was not disruptive - the earlier animist beliefs of the country were simply assimilated into Hinduism - or the opposite could also be said to be true - that Hinduism was assimilated into the animist beliefs of the country . It is impossible to tell , because both played an equally influential role in the people's lives after the shift .
The story of royal patronage is also interesting . The kings of Indonesia , wanting the semi-divine status the Indic religions would grant them ( The Divine Rights of Kings , or rather , its Indic equivalent ) , chose to literally
import Indian priests into their court to perform the ceremonies which would grant them that status . The aristocracy naturally emulated the king . The educated common people , once they saw that the new religion did not displace the old , embraced it in emulation of the king and aristocracy . And following their example , everyone else adopted it too .
It is also interesting to note that Indian influence acted as a booster to Indonesian civilisation . Many cultural achievements which would not have been possible to a culture so fragmented as Indonesia were made possible , after which the Indonesians surpassed themselves . India acted as the spark that ignited the flaming torch of Indonesian achievement , as a sort of quick starter .
Islam , on the other hand , was a disruptive thing . It could only spread to Indonesia because it had snuffed out the central civilisational light of Hinduism in India . The full effects are visible today - Arab missionaries are doing their work in Indonesia , trying to destroy the last remains of animist and Hindu belief and culture , and trying to substitute in its place their Arab fantasies of the pure faith .
And the worst part is , it's working . Aceh , one of Indonesia's conservative provinces , has already adopted Sharia law . More will follow . And the indigenous culture of Indonesia will be completely destroyed forever .
