I have a romantic view of referendums: I don't believe that decision taken via referendum can be wrong. It's the quintessence of democracy and I ultimately believe in democracy, which means I believe that the majority votes as best as the can.

IMHO you're misunderstanding: Listening BBC Radio 5 the last couple of days I can say that lack of transparency, austerity promotion and the way countries like Greece (primarily), Ireland and Portugal were treated in 2014 and 2015 by the EU played a major role in turning voters to Brexit.

Having seen first hand the British media (both English and Scottish) coverage of the debate surrounding the EU referendum, I can confidently say that part of the British electorate has been mislead to think all blame are on the EU institution. There is also the antiquated notion of Nation-State that does not apply to the UK as Northern Ireland and Scotland have voted to remain and are now seeing their future outside the EU against their will.

I had to look up plebiscite, which turns out to be a synonym for referendum (as far as I can tell). As a result, your comment is kind of cryptic.

David Cameron has resigned as a consequence of the vote. This should give you a hint of why I call this a plebiscite for the Tory leadership (and by extension the most liberal politics they prone at home and abroad).
