This neatly ties in with conspiracies and denying reality. You see, the DUP are throwing their toys out of the pram, because the Irish sea border is making it harder to get deliveries from that wee racist island off our west coast, which is leading to bare shelves in our supermarkets. The aim of this big fuss is to get the Irish sea border removed.
However, and it may shock you to learn this, the DUP don't always act in good faith. A cynical person might suggest they are scare mongering, engaging in a project to cause fear one might say, in an effort to start panic buying like at the start of the pandemic. Then they could point at the empty shelves and demand the Irish sea border for the good of the people who they apparently care about now? Only most people either already have their stockpile from the start of the pandemic and have just been topping it up, or are now unemployed/on 80% wages for 9 months and can't afford to buy £100s worth of groceries on Edwin Poots' say so.
The reality is, Northern Ireland is a net exporter of food. Our main industry is agriculture. Moy park produces something like 2/3rds of all the chicken consumed in GB and Ireland and we could replace all the water in Lough Neagh with milk and we'd still have an excess supply. Anecdotally, their are a few items missing from shelves, but there is still plenty of food to be had, just maybe not as wide a variety.
This is just one of many things that needs to be considered when people talk like reunification is just around the corner. It is not a simple matter of shutting down Stormont and getting some TDs to scooch up the benches in the Dáil. Reunification requires the both governments to dissolve and reform as something entirely new. Essentially an entirely new country needs to be negotiated out. And those negotiations will involve the DUP.
