Let me explain Hinduism to you first: The essence of Vedas say "Ekam Sat, Vipra Bahuda Vadanti" - The truth or God is one, wise men call it by different names. We call it Brahman - The supreme Being. To know the unknown, we represent it by idols. Hindus know that whatever God they pray, it reaches the ultimate. That's why we are secular by blood. That's the reason we go to church, consider allah as god too. A pond can be reached by four different steps leading to it. All paths lead to the same pond. The followers of this Dharma (Sanatan Dharma - Eternal concept) were worldwide. The aborigines of Australia still worship a God called Siva who has a third eye and is smeared with ashes. Who else can it be?
Now kaliyug starts: It is said :'KALOU KALMASHA CHITHTHAANAM' meaning 'In Kaliyuga all minds are impure'. New religion starts springing up. What Jesus said is lost and the saints come up with 99% of the bible (Have you read the Red-letter bible?) to erase the Sanatan Dharma and come up with just one religion, one path and one god. They say all other Gods are fake, all paths are false, only God Jesus exists (Is he God or Son of God??). The same goes with Muslims. The problem starts when each one says there is only one God and that is my God.
That;s the reason we have Crusades, 9-11 etc etc. No Hindu killed any other person to convert him to follow Hindu gods. Because as I said, they respect other Gods by nature of their preachings and from birth.
