Jonathan Haidt argues that we make decisions instinctively and then rationalize them later. It seems Wallace’s play extorts this trait and other elements of human nature to show how regular people can side with horrific ones.
Some ideologies are instinctively disgusting but hard to rationally disprove. Wallace seems to argue that they must discussed until they are understood and we find a clear path in opposition. It makes sense but I still wouldn’t want to sit through his play.
