As for all of these arguments about "democracy", they are laughable. The "referendum" was misinformation on steroids, for example Brexiteers claiming repeatedly during the campaign that obviously nobody was stupid enough to even be suggesting leaving the CU or SM...
The referendum was advisory only, won by the narrowest of margins following extreme misinformation and in any case this is a Parliamentary democracy. A choice was made by self-interested extremists to implement the most extreme possible version that wasn't voted for and nobody sane would have voted for had they been told this is what would be done and how much poorer it would make them in perpetuity. And regardless, even when voters have voted for a manifesto in a general election Governments do not implement the policies stated in them anyway and do other things with no mandate whatsoever. Our "democracy" is beyond a joke at this point so anybody trying to pretend there is some kind of virtue in this self-harm that continues whomever is ostensibly in charge is, frankly, delusional.
I'm not interested in going over all of this about Brexit again because it's all well-documented fact. It's disturbing that some people apparently STILL don't understand what was done or why (although as always, it might be worth asking yourselves "cui bono?" if it's possible some still haven't realised why this happened), or even appear to think that what Teresa May was proposing involved SM membership!
The lack of understanding about why the UK is in the state it is in now or the motivations behind the extreme decisions that were taken without any democratic mandate to do so and lack of awareness in the electorate about the implications - even after all this time to repent at leisure - are very apparent, yet still we have people saying it would be a breach of democracy somehow to reverse damaging choices that never had a mandate in the first place either in the referendum or any subsequent manifesto. It's almost comical, the level of self-delusion that must be involved to maintain such a view, at this point.
The British electorate clearly prefer the prospect of declining living standards continuing year on year while on this issue and pretty much every other aspect of the management of the economy - no matter whom we vote for - we are ruled by spineless fools who haven't the slightest inclination to do anything that will improve national living standards, in fact actively sabotage them further, deliberately.
PPP per capita will continue to fall off a cliff compared to what used to be comparable countries and your children and grandchildren will either emigrate or lead far more impoverished lives.
