Regardless of how people voted on Brexit, the last three years have been pretty toxic.
Indeed Edwin.
But I think a big part of the reason for the toxicity is that the original Referendum itself was pushed through as an internal Conservative Party tactic by David Cameron, with insufficient attention to detailed possible options.
No-one knew if they were voting for a remain, a Norway-style deal, a Customs Union, or a complete No Deal. These distinctions were hardly explained or discussed at the time of the Referendum, and neither were the relative economic consequences of those distinctions.
I was a floating voter in 2016. For years I have favoured leaving the EU on a sovereignty issue, but as the vote got nearer I was less and less sure that would actually be good for people with no financial cushions in any consequent economic downturn. I can see arguments both ways.
Nevertheless, I don't buy the idea that an ill-informed vote in 2016 takes precedence over a more fully-informed confirmatory vote in 2019. The more recent measuring of public opinion, both because of more info, and because it is now not then, seems to me to be more democratic. People sometimes change their minds.
That said, it is entirely possible that the result would remain about the same. But at least then, if options of 'no deal', an 'actual deal', and 'remain' were put to the public, we'd know... on the basis of everything we've now gone into in more detail... what the public actually want, right now.
That would be democracy in itself. If people still want a version of 'leave'... fine. If people now want to remain... fine. We should not be afraid of the democratic will of the people changing (if it has). Otherwise, why do we have regular General Elections - and different governments - if not because we recognise that people change their minds in the light of events and new information.
Personally I think if there is a second referendum, people will still vote to 'leave', just to get it all over with. However, what id far more significant then, is what kind of leave they want. THAT was what was never defined in David Cameron's casual referendum three years ago.
That sloppiness was the root cause of why everything turned toxic. Then he just buggered off.
