I'd lie if I said option 6 didn't play a role. Rephrasing it a bit more pragmatically, I think the EU has potential to move in a better direction without corrosive British influence.
I'm rather surprised you're pro-Brexit, Antonio.
I'm not really "pro-Brexit". Brexit is an absolutely terrible idea for Britain itself, as Britons are soon going to find out - so obviously if I could vote I would have voted Remain. That said, a narrow Remain win would really have annoyed me, because it would have come across as Britain whining and whining about the EU without actually realizing that they'd be screwed without it. This would have meant that any UK government would have taken a more and more Euroskeptic stance, thus weakening the EU further. With a narrow Leave win, people will finally get to see how wrong they were, and the UK's downfall will scare other countries from trying the same trick. From a EU perspective, it's a win-win.
