Look, anyone with half a brain would have ignored the braying of both sides on the divide when the initial vote took place. So, leaving that to one side, the voters gave their response to a binary question with no codicils or qualifiers. Leave or Remain. Both had their upsides and downsides either known or unknown. You cannot thrash around with "facts" that came to light after the watershed. None of them are relevant in the long term. Of the people who were able or interested enough to make a vote,a majority (insignificant in my view) voted to leave. By the terms of that vote it should (but not must) be enacted. And then we pick up the pieces where they fall.
For the record, I voted leave but I am unhappy that the terms of the referendum did not specify a meaningful majority. This puts me at odds with many of my friends and acquaintances who voted remain for perfectly valid reasons. We are all held to ransom by the 12 million who could have voted but abstained for whatever reason. Who knows what they wanted or cared about?
