// Jim 16.04 so, equally, it would be naïve to assume that a Remain vote would not be challenged on the grounds that we did not, never have, voted to join the EU, and that we would just go along with the EU's progress towards unification? //
We voted to stay in in 1975, and, presumably, had the 2016 vote gone in favour of Remain, I suppose that too would have counted as a vote to remain inside the EU, ie equivalent to voting to join. I reject the idea that it is about "going along with" the continued progress to unification, though. Earlier that year, Cameron had negotiated a few minor opt-outs of various aspects of policy, and the UK has never signed up to either the Euro or to Schengen -- nor, I suspect, would it have nodded through some other aspects of continued progress to unification.
I would certainly grant that Remain voters weren't sure of what they were voting for either, but then -- for some of them, at least -- that was more or less the point. A vote to Remain can be interpreted at least as much as a vote to return the issue to Parliament, whose role it is supposed to be, in a representative democracy, to make decisions on our behalf.
For my part, almost all I know about UK law, our constitution etc., especially as it relates to the EU, I've learned since June 2016. How many more people can say something similar? I don't think it undermines the legitimacy of the 2016 vote to suggest that anyone who has been engaged with the twists and turns since then should be more informed now than they were then.
