Christians are murderers because they believe that it is their holy duty to murder all the non-christians, and even the fake-christians, even if they are relatives, as devils.
Muslims have similar beliefs. To some extant jews and sikhs also have some similar beliefs.
Jesus christ is ravana, allah is kumbhakaran, nanak is meghnath, yahweh is shrupnakha, and sonia gandhi is tadaka. For proof go to myspace.com/rakesh5.
