I do not ignore the difference. But the majority of people in the world -- Christian, Jew, Muslim, whatever, have never killed anyone. People who enjoy killing will find a justification in their religion. This is a historic fact. It seems to be easier in Islam because church and state are the same, and because Muslims believe it is their duty to convert the world.
But to an individual who is being forcably converted, it makes no difference whether the force is justified by some abstract idea in a book.
People kill for all sorts of reasons. But they also commit adultery for all sorts of reasons, lie for all sorts of reasons, steal for all sorts of reasons, etc. etc. All have sinned and fall short of the glory of God. It boils down to the fact that people are sinful and fallen beings in need of a Savior. Even you are in that category friend. Isn't it true you have broken the 10 commandments in your lifetime? Have you ever lied - even once? The bible says if you offend in one point of the law, you are guilty of all. Without a Savior, you or I will surely be judged for our actions and will spend eternity separated from God in hell.
