Because all we ever have is the outcome of an vote to go by, in all cases?
I can't believe that this requires explanation, but there you go.
I can't believe you're daft enough to think the outcome of the vote is the salient point here, but there you go.
The point is, this is a discussion about whether Brexit will or won't happen. Personally I have no idea, and anyone who cares to venture an opinion is a better man or woman than I.
However, it's a highly, highly significant point that there can't be assumed to be particular reserves of support from the population for leaving the EU, despite the 52% victory in the referendum. The reality is that it didn't get anything like majority support from the adult population now. Maryz specifically mentioned two groups, one who weren't arsed enough to vote and one who weren't allowed to, who as a bloc were very anti-Leave, and who in a number of cases are quite pissed off about their disenfranchisement and certainly can't be presumed to have any loyalty to an advisory referendum.
This means that if for whatever reason we don't leave, or attempts are made to go down this road, the groundswell of people who are actually going to be annoyed about that isn't necessarily going to be a majority of the population. Sure, there are Remainers who've changed their minds, or who haven't but who want the result honoured. There are also Leavers who've changed theirs.
The majority of our elected politicians currently are not sufficiently wedded to the idea of leaving the EU that they'd do it on principle. That much must be obvious. They'll do what they think will get them elected. The reality is that one referendum result is only part of this, however much you think it should be definitive. So the question becomes, will the possibility that the people will penalise them be sufficiently live to make them push for leaving. Not just now, but at every point before we do leave, including after negotiations.
This isn't me necessarily saying what I want to happen either, or think will happen. I really have no idea. We're in a time of political flux. But one thing I do know is that this is a highly complex picture, and the idea that all we have is the outcome of this one vote is extremely naïve.
