In this paper, I engage with the radical critique of human rights moralism. Radical critics argue that: human rights are myopic ; human rights are demobilising ; human rights are paternalistic ; and human rights are monopolistic. I argue that critics offer important insights into the limits of human rights as a language of social justice. However, critics err insofar as they imply that human rights are irredeemably corrupted and they under-estimate the subversive potential of the moral ideas that underpin (...) the discourse. Building on the idea of human rights as claims, I set out the politicising features of human rights as they are deployed in a practical context of disagreement, conflict, and imbalances of power. I illustrate this discussion with reference to the contemporary struggles of irregular migrants. (shrink)
