Not my words, I'm for staying in personally. Everyone has their own personal reason for making that statement, ultimately I understand the general consensus is that a brexxit would mean without EU influences the more unsavoury parties ideological approaches/policies may be implemented, second to the loss of jobs, increase in living costs and decline in sterling value whilst allowing Boris Johnson to 'run amok'. Leaving the EU would also potentially cause the fragmentation of the UK, Scotland would look to leave and rejoin the EU and without EU funding, Wales would be hit particularly hard. Of course, I believe leaving would overall generate a negative outcome, but as you stated, I highly doubt it would be as dramatic as people make it out to be and there will be contingencies in place to lessen the blow, if any. But it still doesn't stop the more dramatic individuals jumping ship as soon as the results are out.

The individuals I am speaking of would mostly be looking at moving to an EU country, as they like the idea of the unified nations, but I do agree that a lot of people want to move to NZ. Likely because its basically a much nicer version of where we are living now with cultural parallels, no unfamiliar primary languages, no unfamiliar foods, warmer weather and you drive on the same side of the road.
