We are choosing to kill people who die from domestic violence, cancer, heart attack, stroke, dementia, dehydration, hunger, despair so that we can protect the people vulnerable to this quite bad cold
No we aren't. I do not subscribe to the viral hysteria, but (a) it is not a "quite bad cold" and (b) we are not choosing to kill anyone to "protect the vulnerable". The governments of the UK have chosen for us to act in certain ways to protect an NHS that they decimated to the point that it could not even do the regular job of health care, so that it could provide healthcare to the many people who contracted the virus. You argue as though it is quite ok to let the elderly, chronically sick and disabled, and anyone else unlucky enough to catch the virus, die a terrible death, and that is justified to save others dying a terrible death. It should never have been a choice between deaths. The only reason it was was because nobody gave a damn about the public sector cuts of the last 20 years, nobody so much as clapped for the services that support and protect all people - and it's already started that nobody cares again now!
The government may have made the choices, good or bad, about how to handle this virus. You made the choices to let them destroy public services for two decades, and you are making those choices again. If the health service wasn't fit for purpose to handle a pandemic - and we knew it wasn't because multiple reports over the last decade have said so - that was something that the public let happen and cared nothing about because it didn't really affect them, and come a pandemic they'd be ok, wouldn't they? People have reaped what they have sown.
