You've unintentionally proven my point with your analogy. If a large hole in the Titanic was blocked up and a few small ones left, then the ship would have indeed sunk, however they would have had longer to get lifeboats launched and a rescue party in place and less lives would have been lost. Reading back across to Covid, a more proactive approach would have slowed down the spread and saved lives. Yes, Covid would still have killed lots of people but maybe a few 10s of thousands less. The same number would probably eventually have caught it but by then treatments and vaccines would have been in place to save some of them.
I read that and understand it, I have to accept that mistakes were made - but it was a quite unprecedented situation. I also think he got bad advice from scientists, but again - it was something new and even the scientists were disagreeing with one another about what to do and when. I was lucky that I didn't lose anyone close to me to Covid-19 but I can comprehend that anyone who did, would hold the government and Johnson in contempt - I get that.
