I disagree - I think the lack of detail on implementation is precisely why so many Brexiters have ended up disappointed with the reality.
I think your second paragraph lends itself to my argument; Brexit meant one thing for you, and another to everyone else, and so an implementation that a majority were happy with was always very unlikely.
That you view a party manifesto in the same terms is another recipe for disappointment, in my opinion.
But don't worry, Farage will be along with more snake oil once Reform fail to deliver.
You are wasting your (keyboard?) breath.
Two thirds of Brexiteers would still vote Leave again.
And that is most who post on this site.
I don't disagree with all their points. The mission creep from free trade was not for everyone. I don't agree, but can see both sides.
And we Remainers wont forget that a sizeable chunk (who are now revisionist on the reasons they actually applied when penciling that cross) voted leave because of Tory austerity, because of the pledge that all that money will go to the NHS, because we paid a sub (like yo pay for membership of any club worth belonging to) and, my personal favourite, to check NON-EU migration into the UK. Funny how the latter has actually been made considerably worse by leaving the EU.
However, its failure is in the pocket; in the living standards of the average Brit; and in the laughing stock we have become. On this, the arguments on economic decline are unarguable. But our friends on here will argue the point anyway.
Look at the rest of Europe. OK, but we are still in relative decline compared to them.
It was not Brexit per se, it was the implementation of Brexit. Just no. It was doomed from inception for the very reasons explained before the vote. Unfortunately those reasons were complex and, thus, difficult. However, the two (TWO) words "project fear" were easily absorbed and smoothed over all those complexities.
We were betrayed. Err, what?
It was stymied by the "elites". Oh dear.
