or visit faithfreedom.org and it will allay all concerns. 'Kafirs' are those who are NOT ahl-i-kitab (jews, muslims and christians have biblical beliefs, so they are people of the book). This is the traditional approach and islam has forbidden ANY change to this approach. While non-muslims among the ahl-i-kitaab can pay jizya and live subordinately, killing them is not mandated (until a strong circumstance arises). Kafirs, on the other hand, cannot be asked to pay jizya. They have to convert or get killed.
