No, they haven't been proved right, and that's my point.
Firstly, they are from the Express which is the most bombastic paper there is. I criticise the guardian mainly because people treat it with more reverence than it deserves. I criticise the Express because it genuinely is full of shite, or at least it's headlines are.
Secondly, there is not a direct correlation between the stories being compared aside from the mobile charging reference. the idea that farming will collapse and one farmer suggesting some farmers will go out of business are not contradictions. Farms have always gone out of business.
Thirdly, there isn't a farming DISASTER and British fishing hasn't COLLAPSED and there's no evidence that food bills have SOARED due to Brexit.
Fourthly, this kind of cherry-picking of articles can be applied to any argument. So many of the anti-brexit predictions have proven false, so the same headlines can be put together for that.
It's all just weird populist stuff designed for twitter that doesn't actually help move forward the understanding of issues. It's the same approach that Leave.EU did on the other side. Pointless.
