Mexican immigrants are the most anti-Semitic: Surveys show that most Jews are immigration enthusiasts. Critics argue that America is importing a lot of people who are tilting the country in an anti-Semitic direction. But not all immigrant groups are equal. Let's see what light the General Social Survey can shed on this question. People were asked how much they liked Israel with answers ranging from 0 for "like very much" to 9 for "dislike very much." It's not the perfect measure of anti-Semitism, but it's the best I could find with an adequate sample size. Here are the mean scores for immigrants from each country (or region):
Anti-Israel mean score
All Immigrants 3.84
Puerto Rico 3.84
As some people have suggested, Mexicans are anti-Israel, as are Africans. The sample sizes for many countries are too small to list estimates, but Europe, even Eastern Europe, is generally pro-Israel. (Eastern Europeans are probably pro-Israel because many immigrants are Jewish). Japanese and Indian immigrants are anti-Israel, as is the small sample of Arabs. There is a correlation between being a white immigrant and being pro-Israel: white immigrants average 3.73; blacks, 4.20; and others, 3.90.
