" talking the country down and generally preventing the One True Brexit."
Is this irony ?
I sometimes have a problem distinguishing with some posters some serious ones can be really off-the-wall at times

I won't get into whether it is ironic or not because that is a really complicated subject. But what I meant was that whatever sort of Brexit we end up with any problems will be blamed on the fact is was not done in line with the purists and so it will be, as McGrath said, someone else's fault. It will never be seen as a problem inherent in Brexit.
