If you contend they are discriminated against despite holding at least 6 of the 8 presidencies, and despite being by far the most over-represented group, I assume you have some fantastically strong supporting evidence.
Maybe small in the US as a whole, but in the Ivy League they are 17.2% - the 3rd largest ethnicity, almost as large as Hispanics and Blacks combined.
But lets suppose they are being discriminated against. That would require some other group, that makes up a significant % of the Ivy League, to be unfairly privileged (otherwise it would have a negligible effect on the % of Jewish students).
So which group do you think that is? You said Asians are discriminated against, so they're out. Maybe you think there's too many Hispanic or Black students, despite being 11x less likely to be accepted into the Ivy League? Or is it non-Jewish whites, the most under-represented group, that are also the most privileged?
But there is discrimination against asians. So $GP's evidence isn't satisfactory.
