I think sadly there's been a concentrated effort in the UK from the likes of Paul Marshall and other right wing shitstains to import US culture war nonsense to the UK, and it's been broadly successful. GB News launched in 2021, which people described as the UK's Fox News, and now 4 years later, we're seeing Reform take elections. It's not a coincidence, it's a forced ideological shift.
The problem is that the left does not have the hundreds of millions of pounds to match this level of brainwashing. That's why the liberals and the right have controlled UK politics for the last 40 years. We saw exactly how they crushed Corbyn before with their collective might, and as long as they control the mainstream media unopposed, they will crush any new left party that emerges too.
Tbf when was the last time any western media cared about factual accuracy. The only reason we should care about this is because if it comes out it's fake, every asshole in the west will point to it as "evidence" each time they want to claim something China says is fake. But they'll probably do that regardless.
In terms of factual accuracy, what's good for the goose is good for the gander. I'll start caring about the factual accuracy of aid drops when the west starts caring about the factual accuracy of Israel bombing hospitals and killing children.
