I'm Australian and was reading this discussion about Mumsnet which diverged into the UK in general. It was interesting seeing how this place comes across from the outside, but also a bit uncomfortable because Australia obviously has its own - arguably worse - version of the same thing.

Here it often seems more casual and "just saying what everyone thinks", especially around First Nations people, African communities, Asians, immigration and crime. From the outside, the UK version looks more class-coded and blunt around immigration, Muslims, Travellers etc.
I only see the online slice of it for the UK, not the reality on the ground, but are we actually that different? I'd be especially interested in what people who have lived in both places have experienced.
