I know many people who will eat only at kosher mehadrin (very stringent kosher) establishments that employ only Jewish workers as food handlers. Several years ago on a visit to Israel, I was warned never to eat at a place that employed Arab food handlers, "because they will p!$$ and c%@p in the food." But of course, any liberal will tell you the people giving this advice were all "vile, fanatical racists."
The Palestinians have realized they have dug themselves into a tremendous hole. Eventually, they will stop digging. But I don't see how they are ever going to be able to climb out.
