There isn't a single Leave voter, who can honestly say they knew what they were voting for. Even to this day, we do not know what Brexit will look like, because there was no fucking plan. How on earth the referendum was allowed to go ahead with no fucking plan is beyond me, but it was, so there you go.
You can argue that the majority understood the implications and possible risks involved in voting Leave and weighed them up against the potential pay-offs of a Leave vote. You can argue that the majority knew there would be no £350 million for the NHS and did not base their vote on that. You can't argue they knew what they were voting for because they didn't.
And in all fairness, nothing I have read from Leavers, before, during or after the vote has instilled any confidence in them from me. Looking at this thread, at least one Leaver is operating under the assumption that the EU give a shit over how you cook your sunday roast.
They also don't seem to quite grasp the idea of parliamentary sovereignty, despite the huge song and dance they made about it in the run up to the vote. In fact one could argue that the 'vocal' Leavers have a done a complete 180 on the matter, without realising the irony.
It's gone from - Take back control from the unelected elite. Give Parliament soverienty over our country. To - How very dare the Supreme Courts take back power from unelected millionaire Theresa May and give it back to parliament. We demand that soveriengnty be removed from parliament and be illegally given to May immediately.
