What’s wrong with everyday lookism?

Everyday lookism, by which I mean the widespread practice of commenting upon and judging the appearance of others, is often regarded as morally troubling. But when, and why, is it morally problematic? I argue that in many cases everyday lookism is wrongful because it involves morally objectionable appearance discrimination. I consider various respects in which everyday lookism can be morally objectionable in virtue of the acts of wrongful discrimination it involves. I argue that these acts are wrongful when they are demeaning, or when they have unjust consequences whether singly or cumulatively. There are a number of ways in which they may have unjust consequences. First, the appearance norms in which these acts are rooted may be biased in such a way that the acts contribute to creating an unjust distribution of benefits and burdens. Second, these acts may combine to make everyday lookism oppressive in virtue of impairing the personal autonomy of its victims or contributing to doing so. Third, these acts may be unjustly harmful in terms of their effects.
