Now is'nt Judaism the same way?
It is but it doesn't have an ethic of converting nonbelievers like Christianity and Islam. You never hear of Jewish missionaries. You never hear of Rabbi Scheinerman Among the Iroquois or stuff like that. Neither do you hear much of Hindus going hog wild trying to convert people. Certainly both kill in the name of their religion but they don't present you a convert or die option.
Christianity certainly had a long period of conversion by the sword. I would argue secularism is the reason Christian churches no longer unleash such blood baths, although if you look at some recent examples where Christianity was tied to the ruling government, you got modern day blood baths. For example, the Serbs and Croats both believed they were doing god's will and their actions were being blessed by their local religious authorities.
In Rwanda you had Catholic priests helping people slaughter tutsi or whoever seeking sanctuary right in the church.
And didn't Bush claim he talked to god and god told him to invade Iraq. To free the people. Of course.
