When I first raised Scottish independence in Washington DC, people just laughed. I think they were haunted by the spectre of William Wallace aka Mel Gibson going around in a kilt yelling ‘Freedom’. Whenever I raised the prospect of a referendum there would be an audible giggle. You could tell people were just not taking independence seriously and were looking at anybody who raised it as being, in their view, a member of the lunatic fringe. That has totally shifted.
