anigbrowl's comment argued that correlations were bad, and did not mention whether useful ones were possible. Blame them for bringing up political correctness, not crusso.
Would you care to provide your interpretation of "Now imagine that your genetic testing service has a data breach and suddenly you have immense difficulty getting hired, getting credit, or getting a table in a restaurant."
The meaning of that is self-evident - you could be discriminated against because people considered you to be untrustworthy due to the results of the test mentioned in the preceding sentence. Where you and crusso see political correctness - perhaps in the belief that I'm describing such a test as a proxy for some identity group - what I'm actually concerned about is the accuracy and/orpredictive power of such tests. I really doubt that you would be OK with finding yourself on the receiving end of such an evaluation.
Obviously you're just dragging your feet here. He is not saying whether the discrimination itself is correct, but that if the validity of the tests is not correct this can lead to incorrect discrimination here, the chance of this data ruining someones life in the wrong hands is very high.
Avoiding performing measurements because you're worried about how the results could possibly be misused is a political motivation, not a scientific one.
The primary concern is fragility, not in truth-space. Scientists have ethical responsibilities and pretending that this isn't true is probably how NSA mathematicians justify their work.
