Really?
Starmer might describe himself as a socialist but, apart from the bailing out and likely renationalisation of British Steel, I haven't seen many economic policies enacted by this government which could be described as 'socialist'.
An "Ultra authoritarian state with zero freedom of speech": If you were in the UK, you would be perfectly entitled to make your views known and I doubt very much that you would be told to be silent.
Unlike China, the Labour government does not operate a system of state capitalism; the UK is very much a market driven economy. When it comes to dissent, unlike China there is no risk of you - or anyone else for that matter - being lifted off the street and taken away for re-education.
Does the UK have a " ... huge, overbearing government just like China" as you claim? I'd say the evidence suggests otherwise.
