"Harm that is both genuine and unfair", then? Income taxes are 'fair' (and I would find it baffling to call that 'harm' unless they somehow came as a surprise), getting fired is offensive if it's done solely because your manager doesn't like you, but fair (and therefor not offensive) if it's because you failed to do the job. I think getting mugged is a good thing to get outraged about - we want to make that happen less!
