The correlation between being an “elite” university and one that tolerates and encourages anti-Semitism has been widely noted. Frum Jews aren’t all that affected since while some of us attend or work for such schools, we are obviously aware of anti-Semitism since we are obviously Jewish – though some “modern” Orthodox do change their personal names and modify their appearance so they won’t look “too” Jewish. For us it has always been a fact of life.
For the more assimilated, Oct. 7 and the aftermath are an existential shock. They never could imagine that those they saw as colleagues felt that the mass murder and rape, etc., of Jews was good public policy. The good American Jews assumed that anti-Jewish prejudice was only directed against frum Jews (and such assimilationists held such views themselves). A similar event occurred just under a century ago when highly assimilated German Jews discovered what their beloved German countrymen really thought of them (and the meme of a German Jew being led to the gas chamber shouting about his medals earned fighting for the Kaiser)
One option is migration to the “red” states, and going to politically conservative (or at least moderate) universities. We can also join the many conservative voices attacking the manner in which credentials from “elite” universities are afforded a value not reflected in the quality of education the students receive.
But the bottom line, is that if the anti-Semitic elites continue in power in America, it is unlikely that the country will remain a good place for Jews, and also that Israel needs to be prepared to stop depending on the United States for assistance.
