There's a lot of batshit on Tiktok! As I understand it, the algorithm means that if you've seen a couple, you're then likely to be shown more. So you won't be getting a remotely representative sample. The majority of the UK population don't even use it.
One of the worst things that happened during covid was that some people started thinking of lockdown as a thing that automatically kicks in once a pandemic happens. But it's not, it's something that was able to happen during a very specific set of circumstances that might never even be repeated.
I completely understand having trauma from some of the worst aspects of restrictions last time. But the money issue alone means it's not happening now, to say nothing of the lack of public trust in public health messaging now. I don't say that lockdown could never happen again, but it's going to take more than a few years.
