Arabs as orcs: I’m not sure whether that’s accurate, or an insult to the orcs.
Orcs are mindless soldiers with superhuman strength and not a drop of pity in them. Arabs have minds and they are very smart, only they are practiced in deceit, treachery and terror. Orcs don’t seek out infants to murder, but if they’re hungry or they’re in the way, they’ll do it. Arabs, however, make a point of targeting infants, before they grow up and learn how to fight back.
On the other hand, there are instances in which Arabs have behaved decently and humanely, such as the Mukhtar of Hevron who in 1948 saved famous (in Israel) singer Yehuda Loichter’s grandmother from the angry mob with his spear and fiercest grimace, and then had her and her fellow survivors of the massacre in Gush Etzion delivered to safety back in what was then all that remained of the infant State of Israel (missing Gush Etzion, the Old City of Jerusalem, Chevron, and many other important parts). Orcs, conversely, have never shown magnanimity. The one Orc who stood up for Frodo’s two cousins was the commanding officer, and would have been held responsible if he had allowed them to be eaten.
