The article doesn't say that. The Army test before it seems to fit that description, but my reading says what would become the SAT was simply to keep stupid people out. The fact that the test's author thought "stupid people" would consist primarily of non-Nordic not-white-folk not withstanding, the test is what brought college admissions equality, or at least more of it, to minorities and immigrants.

seems like the kind of thing that pretty much everyone except racists would be for

Even if it were admittedly design to keep out minorities, the fact that it backfired and did the exact opposite is enough for me to support such a test. So you're calling me a racist? Can't we just have an honest discussion?

The test is in fact meant to discriminate between people, in a purely mathematical sense between those clever enough and those who are not.

So unless you can pinpoint where the methodology is flawed, I would recommend you to go and look up the story of "the boy who cried wolf", before running around and accusing everybody you don't agree with for hate-crime.

Careful: labelling people, no true Scotsman style, is not a great way to push an argument. And it's clear that there is a real problem that needs to be solved (assessing students), so however poor the SAT is at doing this, you're going to have to provide something that can replace it.
