Maybe I'm taking the wrong attitude to this.
Brexit passed by the thinnest of margins, but when we realize that Brexit will probably cause the UK to lose Scotland and Northern Ireland, the level of support for Brexit in what will be left of the UK is way higher than the result in the referendum... and probably still holds a majority in those areas.
So maybe it would be fair for me to take an attitude of "you made your bed, now lie in it" toward Brexit.
I do feel bad for London, though. On the whole, they didn't ask for this, but they aren't going to be able to get independence as easily as Scotland could.
... and I feel bad for the people who are going to suffer with Brexit shortages. Yeah, it would be easy to slip into schadenfreude when someone's so xenophobic that they'd vote to cut off their own insulin supply (and to boot their nurses out of the country) in order to keep immigrants out, but it doesn't bring me joy for even a racist to lose toes to uncontrolled diabetes.
