If I'm honest, I would love the anti-BREXIT fairy to come along, wave a magic wand and tell me to wake up out of a bad dream. My personal view is that BREXIT is and will be a disaster. Almost all my working life has been dedicated to opening minds to Europe, so it would be surprising if I weren't just a tad gutted. My children take free movement for granted, so this all seems like pulling up a drawbridge for no reason at all. I have serious reservations about Cameron's judgment in calling for a referendum.
Nevertheless, it's happened and I agree with you that we don't want to go down an American-style route of deciding whether the referendum was constitutional or not. We should get on with it and make the best of it. I seriously think the best will be a disappointment to the people who voted Leave and we'll be knocking on the door to be allowed back in - maybe not in my lifetime, but certainly in my children's lifetime. Future historians will struggle to understand why we wanted to leave in the first place, because it's not rational.
I don't think that keeping the public informed is catastrophising. I live near Cambridge, which was one of the few areas to vote Remain, and people I know personally are already seeing real (as opposed to threatened) effects. The area has world-class research facilities and people are already finding themselves excluded from funding. The father of one of my pupils was at an Innovative Medicines Initiative meeting in Brussels last week, but felt himself sidelined. These contracts are worth billions of pounds, provide jobs and produce exports for the UK, but we're already beginning to see that people are twitchy. Research projects have been cut and investment is drying up - and we haven't even triggered Article 50 yet. It would be stupid to pretend everything's OK, because it really isn't. Hopefully those who voted Leave can come up with some solutions to the real problems the UK is going to face.
