Jews are fairly unique for keeping their prejudces to themselves. But when you get do really know some, and they don't like to talk about it, they have learned the hard way to be cautious of certain people. The only reason any Jews are alive today is because they didn't trust some group.

My in-laws came from a split of family back in the Poland and Austria. Some people had decided that Poles and Austrians would never let Jews live in peace and moved to America, some of their family and friends accused them of being closed minded and prejudiced. Again who survived?

After World War 2 most Polish Jews wanted to stay in Poland. Generally some more than others, with some being hard core Communists. After progroms and the Anti-Zionist purges the Jews who were better off were the ones who most distrusted the promises of Poles.

Unlike Australians and Irish who wear their Jew hate as a badge, Jews have learned to be cautious of some ethnic groups more than others not from just culture, they are one of the few people who EVOLUTION has selected caution in. Jews who didn't trust Poles were more likely to survive to 1950
