- We just changed our PM, despite his party having a historic majority.
- Parliament routinely rebels against the government, and backbenchers have a lot of say about the business of government.
- We have a number of upstart parties; they might be populist, but at least it's not a two-party-forever system.
- We had a coalition government just a few years ago.
- We changed our constitution a few months ago (abolishing hereditary peers) and it was just another news among many.
- We ejected one of the previous PMs for having a party during a lockdown, with a massive scandal before that when the PM accepted a gift of some wallpaper.
Compare and contrast to the ossified and corrupt American system, where the president is openly enriching himself and his family and friends, and there's nothing threatening the presidency. The last amendment was passed half a century ago, and there's zero hope for reform.
Democracy is a living, breathing system of government, not a number of checkboxes like "can I shoot a gun for fun" or "can I call someone N-word online". It's important to see the forest for the trees.
