Get a clue.
If you wish to take the position of an apologist for Islamic fanatics or the religion of Islam itself that is your perogative but don't attempt to equate the Bible and the Qu'ran. Christianity is based on the person of Jesus Christ, the Son of God. He fulfilled the Old Testament Mosaic Law which was only a forerunner of His coming.
Jesus Christ preached peace; not anger, not war. Almost all of the original disciples died very unpleasant deaths for preaching Christ to a pagan world.
The Old Testament is violent but the violence is mostly of God's choosing. As God created man and supplies the very air, food and water we need to exist, He had the right to do as he pleases when his creation displeased Him - and He did, often using men of His choosing to kill other men who had displeased Him by rejecting God - or His laws. When Christ came the old laws passed away - although the Ten Commandments stand as a distillation of those laws.
Islam is a religion of violence and hatred for 'infidels'. That is an inescapable fact. Soothing essays that purport to explain to non-Muslims how wrong those crazy Islamic fanatics are fall flat when the example of the Muslim world is that of hatred and if not violence, cheering of violence when performed by others, all claiming to be doing the will of 'Allah'.
I don't buy it and I don't accept attempts to equate Christianity - a true religion of peace that so many have died for at the hands of those opposed to Christ - with Islam, a religion of hatred and anger, manifested in the fanatic sect of Wahhabi that schools young men in jihad and ends with hijacked airliners being crashed into tall buildings and 3,000 innocent people dead while apologists prattle on the internet about Islam being a 'religion of peace' and attempt absurd comparisons to the Old Testament Bible to equate Islamic religious violence and Christianity.
Christians don't base their religion on any man, they base it on Jesus Christ, Son of God, mankinds savior. Jesus was without sin and He is our guide, not the Old Testament, some backwoods preacher or TV faker waving a cross and a Bible.
For Muslims, Mohammad (and his Qu'ran) is their guide. He called for death to infidels (non-Muslims). That alone is enough of a difference between the two religions to make comparisons a waste of time. You are free to take the book of Leviticus as whatever you wish but Christ is the Christians guide, not Leviticus - or any mortal man.
