I grew up one mile from Mexico's border in a 100% Mexican-American community during the 1950's. There was one Jewish family that lived on the "white" side of town and one "black" family that lived on the Mexican side. The head of the Jewish family had their business on the Mexican side of town, an army surplus store, and was the only person willing to lend money to Mexicans and was an honest businessman. The black family was accepted by the Mexican community. Yet, I remember the phrase "No seas Judio" ("Don't be like a Jew"), long before I knew who the phrase was referring to, even though I knew it meant "Don't be stingy". Blacks were similarly referred to as being dirty, lazy, and immoral even though our only black family was a very decent, clean and very religious family. I think when a population is being "kept down" as the Mexican-Americans (and Palestinians?) were at the time, they looked for someone they could look down on in order to make themselves look better so they chose stereotypes of people they knew nothing about. Now, the area I grew up in is totally in the control of the Mexican-Americans (economically, politically, and socially) and that discrimination has disappeared in the new generations. Make of that what you will.
