It’s relatively easy to skate over the significance of the Love Ulster rally in Dublin. It’s not likely to be huge. And it won’t be as colourful as the initial march last October. But a delegation will be civilly received at Leinster House, after what march organisers hope will be a peaceful march through Dublin. None of which would have been conceiveable even five years ago, never mind ten. It’s hard to escape the conclusion that Unionists are determined to ‘get outside of the traditional envelope’.
