How on earth can weakening ourselves financially and in every other way be a sensible way to bring about "regime change"?
Many leavers objected to the grip that the EU has over the member states, run by unelected leaders whose accounts haven't been audited and signed off in over a decade - and the mission creep from what was only originally ever sold to us as a trading agreement.
Maybe they believe that this is a price worth paying (at least in the short term) for independence. The same would be true initially for Scotland if they did eventually leave the UK, but people seem willing to accept that independence for many Scots might mean more to them in the long term than some short-term economic woes.
Nobody yet knows how things will pan out when (if) Brexit actually happens - in both the short term and the long term - but a lot of leavers seem determined that their fears have been scientifically pre-vindicated and that every single Brexit voter only did so on the strength of something that was written on the side of a bus and/or because they must 'obviously' be racists.
It's like (some) vegans who patronisingly assume that omnivores can't possibly realise that meat comes from dead animals and subsequently campaign endlessly to 'educate' people of this extremely well-known fact which will enable them to make 'THE right decision'.
If you really think that all Brexit voters were won through what they read in the Leave-side literature (and, going on how some remainers are reacting, one could be forgiven for assuming that all leavers must be too stupid to be able to read anyway), ask everybody you know if they have EVER read a party election manifesto in full (let alone just the last one). If, as I suspect, you find that the answer is a tiny percentage, I presume you'll be campaigning for every future general election result to be instantly overturned and re-run until the result is one that you're happy with.
Why the the leavers so scared of a second vote?
Why are (some) remainers so scared of democracy?
