that all seems entirely reasonable, steve. however, i can remember during the debate on the brexit vote no-one wanting to leave was interested in 'reason' or 'facts' and mocked the opinions of experts or suspicious intellectuals. you would have thought that given the shambles of the last 18 months and the fact that the costs and difficulties of leaving the EU become more apparent every day that most people would have started to appreciate a bit of common market sense. it ain't happening though - in fact the complexity of the whole business seems too much for people to understand or even engage in. so it's left to the elected politicians, career bureaucrats, suspicious lefties and traitorous professionals to do all the hard analysis that they (we) never wanted to do anyway. no wonder that leavers are suspicious of remainers' motives - they should be.
i suspect that they will lose interest and drift off to some other new moral outrage to bang on about and the serious minds involved can legislate the exit away, drop the subject and sneakily (keep it quiet!) stay in with some meaningless trinkets (you can have bent bananas again! isn't britain great?) to appease the gullible and bored. hope so anyway
