No one would support it if it were against Jews instead of Asians. And in fact, Yale used to have this policy against Jews! Absolutely disgusting.
In 1935 Yale accepted 76 applicants from a pool of 501. About 200 of those applicants were Jewish and only five got in." He notes that Dean Milton Winternitz's instructions were remarkably precise: "Never admit more than five Jews, take only two Italian Catholics, and take no blacks at all."[1]
It's quite bizarre how we realized that quota system was unethical so dismantled it. But later re-established the same system but think totally fine because we changed the numbers?
