Yes, that’s pretty much it in a nutshell. We never mentioned the EU because its effect on our lives was passive and benevolent, and all the bad stuff we hear nowadays is practically all untrue.I think everyone's over thinking this. 5 years ago I never heard anyone,ever, discuss membership of the EU. Some people went to Europe on holiday, some people moved there for a bit of sun. Some people worked there. Some people had their plumbing done at a reasonable rate. Most people had never been there or to London or Southampton. Then, a few people, who had enough money, thought they could make some more (or were afraid they might lose some) and manipulated the above and succeeded. Now us plebs are arguing whilst they are smurking.
Go to the Irish border, though, and the people there will undoubtedly have a much more positive view, because the whole of their peaceful existence for the last 20 years is founded on the role played by the EU.
