For what it's worth, I wouldn't ever call someone daft for voting the way they did. The campaign from both sides was incredibly poor and I dare say a great many people voted in ignorance of the issues they were being asked to vote upon. This has been a historic problem, with all stakeholders in this doing a poor job of engaging the public in just what our involvement with the EU involves. In some ways, the referendum has been beneficial as it has forced a lot out into the open, and I suspect many are much better informed now than they were when they voted.
What I struggle to understand is the sheer mental gymnastics some folk are performing when presented with clear evidence that they're wrong on a topic, and a steadfast refusal to update their opinions based upon new, and often better, information. That is something I can't ever idly accept, as an uninformed electorate undermines the very democracy so many claim to care so much about. If you look back over the tortured history of this thread, I suspect you can sense the sheer desperation with which people approach having to go over the same thing for the umpteenth time, correcting the same mistakes again and again and again.
In much of politics you can disagree on how to skin the cat, yet agree that the cat needs skinning, but we're way beyond that on Brexit imo, and we're having folk disputing that the cat has four legs.
