["The British Journal of Sociology, EarlyView. ", "\nAbstract\nThis article explores how boundary making proceeds after protracted conflict has ended. Drawing on an interview and focus group study in two local areas in Northern Ireland, we identify the diverse forms of everyday boundary work amongst moderates who distance from the ethno‐political blocs: everyday universalism, agonism, transformation and cosmopolitanism. Each overcomes closed exclusivist boundaries and identity oppositions, thus providing a clear contrast with the overt political contention and polarization that has followed Brexit in Northern Ireland. Our research shows the internal shape and diversity of the moderate constituency who support peace‐building and a less‐polarized politics. It also offers an answer to the question how such everyday openness coexists with continued political polarization. We trace the different political perspectives associated with each form of boundary making and argue that this hinders political cohesion amongst moderates.\n"]
