Richard Reeves, “Why Some Are More Equal Than Others” - https://literaryreview.co.uk/why-some-are-more-equal-than-others. My own work approaches this idea through the paradox of tolerance, i.e. that tolerance is not infinitely extendable. To create spaces of equality we are obligated to oppose the intolerant. It is also worth noting how religion and religious ideas have informed our thinking on these matters. As Habermas has noted, tolerance arises as a 17th-century legal matter in response to religious diversity.
