Thats fair enough, re NZ, though I do think your interpreting her smile in a way which suits you, whereas to me she was just responding openly to questions put to and her presenting herself in a positive and honest manner.
Whereas Johnson does the opposite, uses smoke mirrors and downright lies whilst often planning (if he does plan) to do the exact opposite to what he is saying.
The bit about a two tier society is moot, I mean we already have a two if not multi tiered society in the Uk and most countries. Those with wealth and those who are poor, plus the people like you and me in between. Its a bit like when I used to discuss health care in the USA with some Americans, who saw government provision of free or even just affordable healthcare as "big government", apparently not being able to afford proper healthcare and suffering serious health issues or premature death was just part of the price for being "free".
If I look at the pure statistics, 28 deaths in NZ and 120,00 plus deaths in the UK then I would kind of think that maybe the "freedom" you are so concerned about is a moot point, after all nobody is being forced to have the vaccine, just that a number of activities may be limited if they don't on the basis that its for the common good.
Tbh I can't se how NZ can do anything else, they cannot practically be cut off from the rest of the world for ever and without high levels of vaccination, then when they do open up Covid will rip through the country with disastrous consequences.
Your comparison with Sturgeon is IMO not valid, her sole political aim is Scottish independence, therefore her actions and rhetoric inevitably lean heavily on this, IMO the case is flawed, but hey ho people are seduced by attractive messages about "sovereignty" and "taking back control" even when they have absolutely no idea about the practical consequences.
On the other hand, the Conservatives are slipping through legislation which is far more worrying, restricting the courts power to challenge potentially illegal government decisions, trying to restrict the independence of the Electoral Commission, restricting the right to demonstrate, trying to subvert international law and convention in turning migrant boats back even if it means their death, restricting a citizens right to vote by requiring ID, the list is long. Now those measures are authoritarian and represent a real threat to freedom and democracy.
