The UK government is trying to make citizenship a political concept. Unless you support the government's ideology then you are an enemy of the state. But your citizenship != political ideology. British people are not the sum of the ruling government of the time. This is why you need a written constitution to protect citizens from oppressive governments.
> British people are not the sum of the ruling government of the time
Not true, the government has been voted in successive terms with majorities. There is a saying that the electorate is never wrong when they choose a government.
The terrible voting system is mostly to blame here. The current government got a minority of the votes (43%) but that led to a huge majority in Parliament. (Obligatory CGP Grey video: https://www.youtube.com/watch?v=s7tWHJfhiyo)
In 2019, their share was larger than any other party (Labour got 31%). Under which reasonably fair system would they not have ended up with a majority large enough to form a government? You may not like it, but the Tories were the choice of the UK population. And you may not like FPTP, but we had a referendum about switching to the Alternative Vote system in 2011—only 31% voted in favor.
Quite obviously they should have got about 43% of the seats. They might still have got a majority by teaming up with other parties to making a grouping of over 50%, but they would have had to moderate their policies for that. (Almost every other party in the election opposed a hard Brexit and wanted a second confirmatory referendum so that would have been different, and better).
There was indeed a referendum and predictably many voted against because it wasn't pure PR, not realising that this would later be used against them, as you are doing now. This doesn't change the fact that FPTP is objectively the worst form of democracy.
Effectively two party system means that no matter how badly the ruling party screws up and gets voted out, all they have to do is wait until the other party screws up and gives them the power back. Pendulum government and FPTP voting is not a real democracy.
