No, but we still don't know, this really is a fear factor built in by non democrats. When we leave, and assuming our economy is ok, I will love to see you lot come back and say you were wrong. If our economy does take a dive I too will hold my hands up.
Yellowhammer was drawn up as a tool for the current government and they tried to bury it. You can bang on about fear but that's like sticking your head in the sand. I don't know what your financial position is but I'm guessing you wouldn't suffer too much from a down turn in the economy. Others won't be so fortunate.
That said, if there were to be a second referendum, your vote is not what remain would be trying to change as you're too entrenched, as is the likes of Bashlsdir and PPF. The difference in the referendum was about 1.27m votes. Only need to change 650k votes. All sorts of things will have a bearing, eg mortality rates over the last three years, the electorate being more educated about the EU and possibly an even higher turnout.
