   First, the DRR is a moral constraint, one that applies to people in virtue of the fact that they are citizens of a liberal democracy. As such, it need not be encoded into law, enforced by state coercion or social stigma, promoted in state educational institutions, or in any other way policed by the powers that be. Of course, advocates of restraint are free to argue that the state should police violations of the DRR (see Habermas 2006,  10).[5] Perhaps some liberal democracies do police something like the DRR. But advocates of the standard view needn't endorse restrictions of this  sort.[6]
