Absolutely not my reading of these interesting, informed, wide-ranging and generally balanced threads.
The idea that the UK is a terrible place to live.
People don’t say this. People do rightly comment on terrible situations, for example the understaffing in the NHS, which is dangerous. The UK is in many ways a very good place to live, and people acknowledge that.
The idea that other countries are not facing the difficulties we are.
Different countries face different difficulties. Pointing out that (some) other countries do (some) things better (even if only marginally better) doesn’t constitute believing that other countries don’t face difficulties. Since Brexit the UK has consistently proved to be underperforming on the international stage over a range of comparators.
The demonization of all politicians when in the main they're decent people trying to do a good job.
Not on these threads, which are generally nuanced. Disliking what a particular politician does at a particular time doesn’t constitute demonisation. For example, I dislike Johnson. I think he has done untold harm to the country through his ambition and duplicity. His wrongdoings are real and documented. But I don’t think he’s evil. Braverman too is judged by her actions, which appear to be cruel and spiteful. She also appears to have broken the ministerial code. But to say this isn’t demonisation, it’s an expression of (widely shared) opinion and confirmed fact. Similarly, I disagree with or disapprove of politicians from other parties and countries, but I don’t believe that all politicians are dreadful.
