Many leavers I've read/heard talking about it are idealistic. Many have aspirations that are laudable but not grounded in reality. They don't seem to understand economic affects or political processes. They can accept short term market wobbles, but don't understand the relationship between that and their jobs/pensions. They can talk about leaving without understanding how many international agreements underpin our modern life, how long they took to negotiate and how difficult/time consuming they will be to renegotiate. That's why they offer bland, pointless answers such as: "We'll be fine" and "We're in control of our own destiny now."
They claim they've thought about it (and they probably have a bit) but it's clear to the rest of us they haven't thought about it very deeply at all, otherwise they wouldn't take such risks.
And at heart what they want is pretty selfish - to be able to set their own fish quotas, or to have the benefits of EU membership - common market etc but without the migrants.
And they've been lied to, for years, by newspapers like the Daily Mail and the Telegraph and more recently by politicians who should know better.
So I guess all these things mean they are unlikely to be repentant, even though they bloody should be. But, to be honest it's not our job to hold them to account or bludgeon them into admitting they were wrong. I think at this point it's our job to hold our useless politicians to account. I'd rather hold Boris to account than see him elected as prime minister - he's brought about this disaster and he doesn't have the negotiating skills to fix it. Honestly, I think we should exhaust every avenue to make sure he's never allowed in office again...
