I'm trying to figure out what you mean. Experts forecast Brexit would hurt the financial sector, Northerners said they were cool with that, the forecast was wrong, Northerners were upset. Nothing about that sounds illogical. Vindictive and short-sighted, sure. But everything follows reasonably.
I say this as someone who's stomach sank when I'd heard that Brexit had passed and that there was a real chance that Donald Trump could be elected.
