You can't, nor can anyone, possibly claim to know the mind of every Arab, or even a majority of them. To claim so would be small-minded and ignorant. This obviously differs from country to country, from sect to sect, but more signifcantly, from person to person. The fact that you seem to think that more than a billion people all share the same mindset is stereotypical to put it very lightly.
That is what the British thought of the Indians, the Americans (and others) of Africans and what to an extent, what Hitler thought of the Jews and Gypsies. Its is convenient excuse to unleash whatever hell you think necesarry, because all they understand it if force.
Please don't assosciate "Western" thinking with everything that is good and just (freedom, moderation, tolerance etc) and thereby imply that anyone who does not fully embrace Western ideals is morally inferior. Its simply not so. There seems to be this great myth that Western ideals are, self evidently, the best, and should be forced down the world's throat. Even people who do not want to use that wording, who would prefer to export Western ideals peacefully, still believe their thinking to be the best, and worthy of establishing around the world. That is, in a word, very intolerant.
