I think the trouble was that the idea of Brexit was so woolly that people voted for whatever hoped it would be. Reducing migration, having all the non-whites kicked out, no more EU migrants taking our jobs, England being the ruler of the Empire again, making our own laws instead of being beholden to the EU etc etc.
It was like saying to a group of friends ‘let’s go on holiday together’ when I expect 2 weeks on a beach, Susan wants 3 days looking round museums, Anne wants a week skiing and Laura wants a month touring Scotland in a camper van.
The fact that Brexit has been a shitshow that didn’t have any benefits is no surprise and all the guilty parties just blame the fact that it wasn’t the Brexit that they said it would be, so not their fault.
