So I guess we can say that Christianity is also a violent religion.
Deuteronomy 13:6-16 "If your very own brother, or your son or daughter, or the wife you love, or your closest friend secretly entices you, saying, "Let us go and worship other gods" (gods that neither you nor your fathers have known, gods of the peoples around you, whether near or far, from one end of the land to the other), do not yield to him or listen to him. Show him no pity. Do not spare him or shield him. You must certainly put him to death. Your hand must be the first in putting him to death, and then the hands of all the people. Stone him to death, because he tried to turn you away from the LORD your God, who brought you out of Egypt, out of the land of slavery."
Luke 19:27 "But those mine enemies, which would not that I should reign over them, bring hither, and slay them before me."
Isaiah 13:15-18 "Whoever is found will be thrust through, and whoever is caught will fall by the sword. Their infants will be dashed in pieces before their eyes; their houses will be plundered and their wives ravished."
There's about 1000 other passages in the bible describing acts of violence, mutilation, infanticide, torture, and murder. Context is important, of course, and many of these seeming cruelties disappear when read as such. However, this would not stop a Christian terrorist from interpreting the Bible in a manner necessary to concoct a religious justification for unspeakable horrors, as Pope Urban II did, for example, when he preached the First Crusade in 1095 or as many American preachers did when they used Leviticus to defend slavery.
Political and religious extremists have abused Islamic, Jewish, or Christian scriptures continuously throughout history.
