This is just to provoke thought. I am writing it principally to help myself think about such things.
It takes personal time and effort to protect against state authoritarianism. Action. Words alone will and do cut very little mustard. It is actions by people that are our best defence. We have next to no influence of what others do. We have total control over the choices we make and the actions we do or do not take.
How many times in your life have you made a 'subject access request' or the equivalent in your jurisdiction ?
How many times have in your life have you made a 'FoI' request or the equivalent in your jurisdiction ?
How much time have your spent on educating yourself as to what legal powers the police do and do not have ?
In interactions with the Police or authority in general to what degree have you reacted with a starting point of automatic 'deference' towards them for convenience or any other reasons rather than from a starting point of what are their legally defined powers ?
How much of your precious life have you spent in non income generating activities that could broadly be described as attempts to 'challenge power' ?
I suggest that the real protection against Orwellian state control is action by individuals. By individuals choosing to spend time and effort that is so much more easily spent on other things. I suggest if your answers to questions like those posed above is 'low on the spectrum' and you are genuinely concerned about 'state authoritarianism' then perhaps the best starting point to try and do something about it is in questions like those above and your own personal choices and actions before just righteous pontificating about such issues in places like this forum.
