robomatic, I think there is ample evidence for my statement in Wikipedia and other sources. I am using the term "non-native speakers" for persons who do have some Yiddish-speaking background, but whose everyday language is the language of the country they were brought up in, such as the USA, Israel, or Russia.

In Israel and its predating Jewish settlements, speaking Yiddish used to be strongly discouraged, therefore the language became an emblem of anti-zionist orthodoxy. Reacting to this, zionists discovered the potential of the language and produced or commissioned "folk" literature in it. Examples see above. As usual, other political aspects were added, such as conflicts inside Israel, inside the Jewish community worldwide, and with non-Jewish communities.

Many Mudcatters are unaware of political cultures outside their immediate vision; therefore I added the (admittedly somewhat lame) comparison with Gaelic. Anyone who is really interested will have no difficulty finding more information. Unfortunately I cannot claim to be an expert beyond what I wrote now.
