I know loads who voted 'in' razza, myself included. But then I was voting for a trade area with common standards and free passage of goods. (The other things that came with it did not register as dodgy, as I was young and enthusiastic to build bridges with nearby countries; and thought it was insane to export and import from half way across the globe when there were nearby producers and buyers.)
I may not have voted to join if asked, not that I was given a chance, but I sure wasn't, in those early heady days, going to insist we immediately came back out again. Give it a chance now we were there. And of course I thought that those against were simply spreading fear stories when they warned of it being more than a trade area, and that the elite in this group were wanting to take over control of all member states and make it one large block.
Well it turned out my distrust was mistaken. the EEC turned into the EU, we had individuals from the other member states claiming this closer integration was the whole plan all the time (not for us it wasn't) and so now I'm not so naive: I've years of actual experience to understand what being in the EU really means. What it stands for.
I've also analysed the 'remain' sides arguments against leaving and staying and found nothing that I can think of that "held any water". It's all horror projections that common sense tells you are incorrect, or trying to pick fault (and generally failing) with what the leave campaign has informed us of.
I've reigned in my youthful visions of paradise in Europe in order to accept the practical reality of appointed individuals wanting power, individuals who are happy to manipulate the rest of us with tales of wonderment, backed up with fear of having to be in control oneself, in order to get the influence they crave.
