There's no evidence of anti-Jewish bias in Ivy League admissions (the opposite, in fact), and polls also show friendly attitudes towards Jews among the general population, so I don't know what it would take to convince you. On the other hand, Ivy League students are only 33% non-Jewish white, and 4-5 of the 8 presidents are Jewish, per their wikipedia pages (Martha Pollack is listed as Jewish, but the citations in support of that claim are ambiguous, hence the uncertainty), so what makes you think that admissions are the exception where WASPs reign?
