I support Israel because it represents the aspirations of a small minority persecuted by a big majority, and like most Americans with a liberal orientation towards the world, I realize the need to protect these small minorities from persecution.
In addition, the civilizational values of Jewish people, for the most part, are liberal, modern, and advanced. They are among the world's leaders in environmental technology, produce Nobel prize winner after Nobel prize winner and are a modern oasis in a sea of primitivism.
The Arabs who call themselves "Palestinian" for propaganda purposes, on the other hand, are deeply inbred, regard women as nothing more than brood mares and celebrate mass murder as the highest achievement attainable in their primitive society.
It's an awfully easy choice to make for any who are human.
