I undertook a quick and dirty look into how often the word "fight" or some variation of the same occurred in the Qu'ran and the Bible. Do not leap to any conclusions but the numbers were 94 to nil:
Qu'ran
Bible
First off, it must be noted that the Qu'ran (as opposed to the Bible which was written by a multitude of men in a multitude of times) was written by only one man, Mohamed, who was essentially a military man, a soldier, in essentially only one rather strife-filled era:
Sure, Muhammad wasn’t like Jesus, who preached briefly and, in his life, rather unsuccessfully. He wasn’t like Moses either, who died without reaching the Promised Land. If there’s any Biblical figure Muhammad recalls, it’s David. Both start as humble figures of noble ancestry, and end as powerful rulers. When Muhammad was born, Arabs were divided into hostile tribes. Justice was collective, and turned out rather like revenge. In place of this, Muhammad advocated for an ummah, a ‘super-tribe,’ a union of peoples based not on bloodline, class, or gender, but fidelity to a common and universal worldview.
.... Muhammad was not like Jesus, born into a society with a powerful government. He was born into a place with no unifying government. An orphan from birth, who soon lost what little family he had, knew intimately the vulnerability the unattached suffered their entire lives. He created a system to put an end to that.
David, Mohamed, Jesus, editing, stuff, below:
Second off, Mohamed was a lot smarter -- and better educated -- than David. Far as I am concerned, David was a damned whiner:
Hear me when I call, O God of my righteousness: thou hast enlarged me when I was in distress; have mercy upon me, and hear my prayer. Psalm 4:1
O Lord, rebuke me not in thine anger, neither chasten me in thy hot displeasure. ... I am weary with my groaning; all the night make I my bed to swim; I water my couch with my tears. Mine eye is consumed because of grief; it waxeth old because of all mine enemies. Psalm 6:1, 6-7
Why standest thou afar off, O Lord? why hidest thou thyself in times of trouble? .... He hath said in his heart, God hath forgotten: he hideth his face; he will never see it. Arise, O Lord; O God, lift up thine hand: forget not the humble.Psalm 10:1, 11-12
And, mind you, David never says the word "fight" in the KJV, he pretties it up with the poetic word smite and various derivations thereof.
Third off, the Bible has passed through a great many editorial hands and a lot of crude stuff (understandable perhaps within the context of the times) has been edited out.
The Qu'ran stands in its original form with no accommodation for changing times and opinions.
And, there is puhlenty of violence in the Bible -- they just use a bunch of code words to disguise it all and pretty it up.
Although in conclusion, in reference to the dispute between Haroon Moghul and Ayaan Hirsi, see above discussion of Mohamed and David in the first part, I kind of think I'm going to end up agreeing with Ms Hirsi.
