I’ll give you a good example. I have a cousin who is a highly intellectual guy. Straight A’s at A level but joined the army in preference to university. Worked his way up the ranks and then left to join what was then the RUC, took voluntary redundancy as part of the measures to cut RUC numbers in the GFA, joined the Met and after many years serving in London has just retired at 55. The guy is a genius (especially history and specifically military history), he’s well traveled, has lots of life experience in many walks of life. He also has a Facebook account and because of his connections to the army, police force, his friend group related to this and his interest in military history he seemed to have become a target for Cambridge Analytica during the referendum campaign. Most of which he ignored but he latched onto something claiming that the EU can force us to join the Euro and voted leave based on this information. To be honest I was staggered when he told me because he is one of the most intellectual people I know. He was unaware that we and Denmark have vetoed out of ever committing to join the Euro. Simply because he’s a member of groups on Facebook that are loyal to the crown. He’s somewhat red faced now but you’re talking about a proud Protestant man from Northern Ireland who has served queen and country in the British forces, the Royal Ulster Constabulary and the London Metropolitan Police Force and the thought of losing the queens face of our money was enough to push him over the edge. Ironically things like they took away our blue passports he knew was bullshit but through targeting campaigning they hooked him in on 1 “issue” that in truth wasn’t an issue. He deeply regrets his decision, he’s just retired back to Northern Ireland and is now facing up to the prospect of a united ireland and ironically adopting the very currency he was duped into voting a certain way to avoid.
