Some of that is worthy of Tucker Carlson - peak conflation. Dilution though is an apt projection - Britain is weaker after Brexit. It's quite a depressing read: up at the top is democracy (helped along by your man Boris; Priti, Liz and our wonderful AG), followed by the economy (projected to sit just above Russia's next year) and sterling (much stronger and sought after whilst we were in the SM, now weak and floundering). Other notables include the Union, trade, rights, farming, fishing, education, travel, employment, wealth, standards, the NHS, small business, our international standing; trust, tolerance, friendships, families and communities - on and on we could go. And let's not forget how much of the nation’s financial resources we’ve depleted to keep Britain in this weakened state. Still, we've enjoyed an uptick in tribalism and right-wing politics (your man again). A quick read of European history tells us where all that leads.
And what of control? The typical Brexiter seems rather fearful, angry and insecure so it makes sense that Take Back Control resonated: control - or at least the perception of control - being the balm that helps soothe uncomfortable feelings. They also seem to dislike being told what to do by people from different lands so again it makes sense that sovereignty, flags, jingoism, Empire and posters about immigrants also worked - wall-to-wall dopamine and serotonin for the masses; however, it turns that Take Back Control is really nothing more than reproducing EU regulations in our own format, and sovereignty is just an unnecessary, expensive and convoluted game of trade-off - between our shiny new rules, which are largely MIA as no one can agree on what Brexit actually means, and access to Europe.
Can’t compare our foreign policy as I’m not sure what it is exactly apart form cutting the international aid budget (rather small-minded I’d argue) and copying EU trade deals. Ukraine wants to join the EU, not the United Kingdom, just to be clear. As for peace, we are much better at war than the EU - and we weren’t in the Euro so that’s a moot point. CAP has helped numerous famers and rural communities, and helped protect food standards but it has also encouraged intensive farming which damages the environment but then again so has every other major country’s agricultural policy but that doesn’t make it right. It’s not all milk and honey in Brussels you know. The comment about out-groups btw refers to the exaggerated (and misplaced) hostility and posturing toward the EU (the out-group in this case) by leave voters. Despite all the copious copy you've not really elaborated on what continues to fuel your hostility for and antipathy toward an organisation that has brought peace and prosperity to so many six years after the referendum. And why are we still the only country to have left the EU? Maybe the EU is not the existential threat you think it is, or maybe it's because our friends and neighbours see Brexit for it is: a failure, and abject humiliation for the British State.
