The UK had lots of concessions from the EU, the Cameron ones were pretty much all the EU was going to offer us further. Is a false to pretend otherwise, that "there was no reform" when the UK had all sorts of opt outs, and exceptions made for it by the EU.
It seems also that whilst there has been an increase generally in the last few years regarding more nationalistic parties, there has also been an increase since brexit for support for the EU.
In the end, remainers do not have a crystal ball, but what we do have is economic analysis by a vast array of different experts that corroborates each others findings, from organisations that have a vast array of different objectives.
When one piece of information says the opposite you remainers cling to it and make appeals to authority, like Carol's misuse of the BOE data, you then fail to note anything that goes against that opnion, like the deloite findings, or the economic activity data released yesterday, the continual low level of the pound and the falling out put from construction and service industries.
If you hadn't shot us all in the foot it might be funny.
