Being “generally true” is different from being true. Lebanese Christians, for example, have had a complicated relationship with Israel in recent decades that I suspect goes far beyond liking or disliking, loving or hating.
Being generally true is the measure of a generalization.
Arab culture is generally quite different from Western culture. We in America should refrain from assuming that the Arab people of any religion look upon Israel as we do. Heck, the American Left has even turned against Israel.
