It shows that what people voted for was never accurately defined. The campaigners supporting the leave side lied about what they saw as an eventuality of the trade scenario. They then countered the realistic predictions of the remain campaign by saying it was fear mongering.You seem to assume that the voters sided with a side irrespective of what was punted by either leave or remain. If that was the case Remoaners lost.
If you are saying the Remoaners voted stay because of the possibility of No-Deal, they still lost. If you are saying the Leavers voted because of listening to both sides and made an informed decision, Remain still lost.
Either way you look at it, Remain lost and will lose again. If people voted against loyalty lines Remain lost. If they voted by making an informed decision, remain lost. You can try and spin it in 300 different ways, the truth was out there between remainers and leavers. People voted for what they saw as being the best. With ALL the information at their disposal from BOTH sides.
I know its usual electioneering tactics. It just illustrates, now with hindsight, which side was more realistic.
