Unless it's 100% remote without any video conferencing, it would be a little hard not know race. The point is being forced to track it by self reporting they can't hide their racism. In this case they're asking about education status, marital status, whether you have kids and a zillion other (mostly protected) statuses. Protected ones you're not allowed to discriminate... now if you have a weird accent or bad fashion sense, likely allowed to discriminate.

Not measuring something doesn't make it go away.
