There are plenty of polls that indicate the claim I'm making, eg:
https://whatukthinks.org/eu/questions/would-you-support-or-oppose-a-second-referendum-on-british-membership-of-the-european-union/
As can be seen, the latest poll in this series actually has the sample slightly against a second referendum.
I know we disagree on the point of whether polls are evidence at all, but taken in their proper context and with due care not to read the headline figures too dogmatically they are perfectly valid evidence.
Also, I don't agree at all that "And no, even if we made a major presumption that the entire country has changed their minds,democracy still needs to be honoured". By definition, in that extreme scenario it would not have been. Because democracy must be based primarily on honouring the wishes and interests of the electorate *now*, rather than yesterday.
Again, I concede that this is a point on which we may never agree, but even if you don't agree can you at least concede that there's a rational case to be made that votes cannot be held to be forcibly binding? If people are given an opportunity to vote, and they vote yesterday all against and today all for a particular viewpoint, precedence would clearly, rationally, be given to today's vote.
