The problem between the communities is not a Jewish issue, it is an American issue. Americans have a disturbing habit of looking down on their ethnic brethren from abroad in this country. As the son of an Israeli I can tell you we did not fit in to the local American Jewish community for three reasons: 1. our last name didn't end in Stein or some other American-Jewish end syllable 2. our ancestors did not immigrate to the United States from Northern Europe in the 1880-1920s time period. 3. we didn't eat the same food or have the same customs or speak "good" (e.g. without an accent) English. Even today the first question asked is when did your family come to America...and the answer better be in the lower digits. Thus we were those "other Jews" who were grudgingly half-accepted by the local community since there was no other place to put us.
