That's probably one of the more astute comments i've read about this. How many labour defectors voted Tory and caught everybody napping? The media are concentrating on buffoons who didn't know what they were voting for but i think that is a misrepresentation. I think a significant amount of people voted for England, not the UK. A disenfranchisement with both the establishment and the course their country is going down as a net recipient of migrants. I've zero sympathy for their post colonial legacy but it shouldn't be be tarred as blind racism, it is racist, all states are racist by the way, but there is an alienation behind it that warrants political discussion.
It's not clear what will happen now which is why I wouldn't pay too much notice to the doomsayers. Assuming they invoke the release clause everything depends upon what deal they strike and in relation to Ireland both the long term strength of the pound and the deal will be critical. There is no grounds for comparison here and the UK isn't Greece. Greece when playing the roulette with negotiators were likely told to F off or accept. The UK is a world leading economy that the EU can't really afford to make a pariah out of. It will remain a leading trading partner. Some euro clearing will move out of London to Dublin etc but hedge funds will fill the deficit.
Other issues like air travel will also be decided upon the deal, will they opt to stay in the EEA for example. Low cost Norwegian carriers operate very successfully out of a non EU country and have even applied to run transatlantic services from Cork. Its hard to predict outcomes here.
The status of the north is interesting. Is a united ireland we can't afford closer than ever if a pro english nationalist govt gets into Westminster? The north can't be dragged into the republic without out its consent and i don't believe that consent would be any way near given but i'd guess the legal framework states it can't be removed from the union. If Scotland leaves and a drive for English nationalism materialises there will be no union.
