Last week, I went to one of the debates at the Cambridge Union about whether or not Britain ought to have a second referendum on Brexit. It struck me that the way this argument works is very misleading. The two sides pretend to be arguing about whether it would be democratic to have another referendum, and frame their arguments around procedural fairness and democratic legitimacy. But that isn’t really what the argument is about. There’s a much deeper disagreement, about whether Brexit is an acceptable outcome in the first place–if it’s the kind of result which, by its very nature, invalidates the process which led up to it.
