In China (based on its Marxist roots) cults and religion are deemed to be damaging to a person and to mass popular culture ("Religion is the opium of the people" - Marx).

But I'm afraid the slightest boost in predictive power will matter to an organization of scale. And while it might be hard to tell if you should be a mathematician based on your DNA, it might be easier to tell risk factors about you or your relatives, which could cause an employer to see you as too expensive.
It's illegal to discriminate on disability, but if I know you're predisposed to heart disease and discriminate on similar basis, is that discrimination on disability if society doesn't classify it that way?
