Assuming you have an accurate individual level test, and the policy action you suggest is to not administer the test to each applicant and instead treat them all as homogeneous group and reject them based on older test results?
Yeah that's a racist idea.
Right, so what's the state policy you advocate here?
Import 1 million people, 800,000 of which are racist, sexist, homophobic and militantly conservative -- and you'll do that because the policy to prevent it is, as you say, "Racist" ?
You may think these imports are on your side for now, because of the cross you've nailed yourself to -- but be assured, as you see today in the US, their cultural conservatism comes out when their social position is safe.
You are importing the very people you claim to despise : racists, sexists, misoginsits, and the like. And you're doing it why?
