lonely That kind of argument is exactly what turns off most Leavers, when we need to engage at least some of them.
There isn't a coherent master plan, at least not one that most Leavers are aware of, or support
This is because the Leave vote was a protest by a huge range of people against modern Britain:
the Left Behind who can't compete in a global market, some wanting to strike at the successful mc, those wanting to end austerity, English / British nationalists, wealthy boomers who want the world of their youth back, the JAMs, ideological hard-left and hard right who wnat to remake the country
.... and also those who didn't understand the issues or the consequences
What many have in common is that they all feel they won a once-in-a-lifetime against those they regard as a hostile elite
They would be bitterly angry to the end of their days if that victory is taken from them.
Where we can have effect is explaining - not lecturing - on consequences to those who weren't angry and are starting to query Brexit
Re the angry, bitter Leavers - at least don't make them even angrier by questions designed to make them feel stupid
They'll be angry enough if we manage to Remain, so don't wind them up in advance.
