The ‘consensus’ model of public reason, associated with John Rawls’s political liberalism, has been criticised for excluding certain reasons from receiving consideration where the justification of the constitutional essentials is concerned. One limitation of these criticisms is that they typically focus on the exclusion of reasons political liberals are committed to excluding, notably reasons based on religious and comprehensive views. I argue that public reason excludes some reasons, central to the interests of many oppressed groups, that public reason advocates will agree should not be excluded.
