May I delurk for a bit? Apologies as I've only seen the last couple of threads so may be echoing you all!)
I am probably, and ironically, more towards the Dementory Scale than most of you 
and even more iconically I'm fucking shielding but by God, I am fucking fed up at the moment with all this bollocks. I am actually trying to shield myself in some ways as I've been ill and I'm quite keen not to die 
but I don't do blind acceptance of rules at the best of times and the current circumstances are really giving me the rage.
I actually (don't shout!) think lockdown and quarantine etc would have been useful tools - but the key word is would. The total fucking incompetence of the government in seeing this coming, doing fuck all to prepare, letting everything get to the stage where we were always going to have completely avoidable excess deaths - and then shutting everything down is staggering. And everyone is obedient and unquestioning of this strategy!
I genuinely cannot understand why the vast majority of the general public are docilely going along with this closing of the stable door and are just shutting up and doing what they are told. (And God, the judging of other people not doing what they are told. Bloody hell). I really, honestly, do not understand it the mentality of it.
The government are past masters at the "look sideways not up" strategy and they want people to say "Janet from No. 3 is literally risking people's lives by sitting 1.5m away from her DC" not "the government have fucked this up so spectacularly that they have caused needless deaths". And people are going along with it!
I'm sorry (dementory, you'll all scoff) I do believe things like face coverings would have and could have helped IF they were implemented earlier. Making people wear them now (and announcing it with two weeks notice, WTF 
) is so horse and stable door-y it makes me cringe.
The likely extension of the shielding and the protect the vulnerable cliches is going to make me angrier but maybe that's another thread. My DC and DH aren't shielding as it's impossible for us as a family (well possible but at too great a sacrifice) but I realise this is personal choice and some people feel differently. I have huge amounts of sympathy for people being told to shield, especially for parents of shielded DC. We are all in a lot of different situations (which is precisely why the blanket DO NOT LEAVE YOUR HOME FOR TWELVE WEEKS FROM THE DATE OF THIS LETTER does not work).
For my own feelings, the government advising me to stay at home "for my own protection" combined with their total lack of giving a fuck for my protection before they panicked, makes me feel very angry and frustrated. I have done so much already over the years to prevent my health fucking up my DCs lives, I'm not about to throw that all away and blindly tell them to sit at home, while
I don't question anything or risk assess anything as an adult - whilst being lectured on responsibility by Boris fucking Johnson.
So whilst lots of you probably think I'm a knob for wanting face masks etc 
I think we have common ground on the feeling that there must be some sedative in the water which is working on the general public. It's truly scary. I actually think we need more outrage but not at people "breaking the rules" at the people who implemented the rules and their ineptitude.
