When I dig into UK stories about people being fined or arrested for social media posts, it is virtually always people who advocate for violence against certain groups, and then right wing media twists it into a "they're jailing people for hurty words" story.
The only reason Britain still has that reputation is because Americans repeat it mindlessly in media that the whole world consumes.
Like the teeth thing. In the 2000s, the UK alongside Germany had the joint healthiest teeth in the world (although now they've fallen to 8th after the Scandinavian countries upped their game). Did it stop the "Brits have bad teeth" gag in US media? No.
The US, for whatever reason, has been engaged in a cultural pissing match with the UK for a long time.
Christmas wasn't really a THING in England at that point
??? It absolutely was a thing. A huge thing.
it hadn't been too long ago that Christmas was banned as a practice in the UK
Christmas celebrations were banned for a 2 year period under Cromwell, almost 200 years earlier. Even then it saw huge backlash and public resistance.
Dickens wrote with the intention of bringing back the Christmases he remembered of his youth
They never went away.
Dickens wrote A Christmas Carol because he was very concerned with the plight of poor people, the working class not having enough time with their families, child labour, and the wealthy keeping all their money to themselves with no regard for those below them.
I truly don't know where you got the idea from that Christmas wasn't a thing, that Christmas was banned shortly before, or that Christmas was a thing in Dickens' youth but not his adulthood.
British food is unironically great, and the stereotype is based on experiences during WW2 rationing. It's made funnier that the people who say it comes from a country where people spray cheese from a can...
There's so many good pies, pastries, puddings, roast dinners, breakfasts, etc that are very good. British-Indian food is often excellent. Even a basic dish like macaroni cheese can be lovely if you make it right.
To be honest unless you include northern France, I'd argue nowhere in northern Europe has better food.
Painting that on a junction like this just seems incredibly dangerous.
