I agree. One has to read entire Quran. Also Hadiths.
In BhagvadGita, Krishna asks Arjuna to fight for righteousness. He does not ask him to fight because Kauravas follow a different religion.
In the Quran and Hadiths, we find several instances of war being urged on other people, for simply following another religion. Kafirs will not only burn in hell forever, they also deserve to be conquered and enslaved by Muslims. Not because they are bad people, but because they are not Muslims.
