I am not versed in the differences between neoliberalism and liberalism, so can't respond to that, but there are quite a lot of other points I would make.
Firstly our sociopolitical model has over decades given us lives which are hugely preferable to those of the vast majority of people in the world, in terms of living standards, freedom, and social cohesion. Of course these things are suffering currently, but I am not convinced that this is because there are better sociopolitical models.
Our living standards are suffering largely, in my view, due to the pandemic, which had a vast cost yet so many of us appear not to understand that we are all necessarily worse off as a result. Our political model may also be to blame, because whilst at heart I am right of centre and prefer smaller government, our political parties will not trust the electorate (probably rightly) with the necessity that personal tax needs to be higher (but the public sector also needs to be forced to be more efficient and productive), trying instead to burden enterprise with all the cost and unsurprisingly stifling economic growth as a result. The other obvious point on living standards is that we are allowing productivity to be constantly eroded, with an increasingly lazy stay-at-home culture and ludicrous regulation. Only productivity improvements can make the country generally more prosperous - that is economic reality.
My opinion is that reduced social cohesion has two key sources, one being the internet which encourages people to listen only to an uncontrolled echo chamber instead of listening properly to a range of views, the other being inappropriate immigration which is leading to significant segments of the population who simply don't share the values the country was built around, and put bluntly therefore have no place here.
Our freedom is being attacked, and that is what we need to fight for. I am shocked to hear that you have had the police knocking at your door because of your opinions - that is unforgivable in this country unless you are seeking to incite people to go out and murder one another. The country is increasingly feeling more like what I imagine the eastern bloc was like before the Iron Curtain came down, though I would also maintain that we haven't got anywhere near that yet. But it is worrying that it feels as if a specific ideology is invading the public sector, and this must absolutely be stopped.
Last point in this essay (sorry, but it is an interesting debate I think), is that whilst the Labour Party only won quite a small proportion of the vote, they won the election fair and square in the system we have, and I imagine it is many decades since the ruling party gained a majority of votes as opposed to seats. The point is that if the population decides it, they can be removed from power, so you cannot fairly characterise their rule in the same way as, for example, Erdogan in Turkey who has turned that country into a tyranny. I may not agree with them, but do not feel tyrannised by them (unless they attack my right to disagree).
