Re: Of course the original referendum is only "advisory" it is not legally backed.
I think it's advisory in the same sense that the rule determining whom the Queen will pick as PM is advisory. Political reality always wins. Brexit could be avoided now only if a majority of people wanted the vote to be overridden and by some mechanism were able to say so — a second referendum, a snap general election, whatever. But I just don't see what convincing argument you could make that the majority of people want a rerun. The majority voted out.
As a voter for remain, I think Cameron et al have made a hash of the whole thing. An issue of such constitutional significance should never have been reduced to a binary decision and decided on by a simple majority. But those were the rules and the exit side won. So — in a democracy — that's that.
I guess that belittling those with concerns for forty years rather than addressing them, then telling them that they were talking about the wrong thing anyway, wasn't such a winning strategy?
