My favourite expansion on Brexit isolationism was written by A A Gill (for The Times, but here risking a bit of infringement…)
The dream of Brexit isn’t that we might be able to make a brighter, new, energetic tomorrow, it’s a desire to shuffle back to a regret-curdled inward-looking yesterday. In the Brexit fantasy, the best we can hope for is to kick out all the work-all-hours foreigners and become caretakers to our own past in this self-congratulatory island of moaning and pomposity.
This week was the fourth anniversary of leaving. Nobody here is celebrating that. At all.
