That is very true.
I used to hold that against David Cameron, since he was the one who called the referendum... and I was also pretty peeved that another referendum wasn't repeated once we had the full details.
But actually, although I was strongly against Brexit for both economic and 'values' reasons, I think the dissatisfaction felt by more than 50% of the population had to be addressed. It's a mistake for the Liberal Elite to think that they always know best.
And I hold Corbyn just as responsible for sitting on the fence about Brexit. Political coward. At least David Cameron and many other Tories campaigned for Remain. It was close enough that Corbyn might have made a difference.
So I don't really hold Brexit against the Conservatives. I know others do.
It's still an absolute economic disaster, and will be for another generation at least. But the EU isn't perfect either, far from it. And we have always had a fundamentally different understanding of the Union than the other countries, which has always been a fault line causing dissatisfaction on both sides. Another poster also recently explained how our different welfare model (which relies on previous contributions in the rest of the EU, but not here) causes a problem for us with free movement.
I do wish we could have stayed in, and worked on it from within - but that's done now. Hopefully we can rebuild some connections. Trade will take a while I think, but political cooperation and information sharing which benefits everyone will come back as the EU (the French in particular!) forgive us. And in a while, we may yet be glad to not be tied to free movement. Difficult changes are coming in the next 50 years, and I think the era of international cooperation as a Western value and end-goal is coming to an end. It's all going to become much more transactional (as it has been for many other countries all along).
