Nope, in the same way that I wouldn't 'congratulate' someone for gambling someone else's family rent on an unknown horse that just happened to win.
If even one Brexiteer could have given us any provable odds over the last 3.5+ years re the likelihood of us *all* coming out of this better off (in all the important meanings of the word), then that might have been something ... but they haven't? In fact, much of what they put forward is no more than hopes, dreams and guesswork, just gambling again.
If it was such a dead cert, why didn't more than 1/3rd of the electorate put their money on it? Why did nearly the same number go against it? Why did it take lies and tricks to scam the vote in the first place?
Are you really one of those people who are happy to take the win because your horse was on steroids and the other wasn't?;-(
Really John, you can usually manage logic and reason better than that. ;-(
