There are two points to consider here.
Firstly, you were contributing to the rules being broken, ergo you should have gone home. Being squashed on a bench with six others wasn’t mandatory, it was a choice you made for yourself. Even if the pub hadn’t put the correct measures in place, you still chose to stay there.
/secondly following vaccination, the death rate and the hospitalisation rate from COVID has dropped dramatically. While there is some concern that vaccinations may not be as effective against new variants, this is an unknown. Added to which, the idea has never been to eradicate COVID, only to control it. COVID is always going to be here. People will always catch it, and they will always die from it, much as they do now with the flu. But we hopefully won’t go back to a situation where it sweeps through the population as it has done in the past year. Other pandemics such as the Spanish flu show that this is unlikely to be the case.
Therefore, there comes a point when we have to open up and allow life to return to normal. There has to be a balance.
I think that there are some measures such as masks which will become a more permanent or at least regular fixture such as in the flu season, and as mask averse as some people are I actually believe that this should be the case. Other countries manage it and have done for years, I don’t see any reason why we shouldn’t as well, especially if it means less hospitalisation and deaths from flu. But we literally cannot stay in lockdown forever. That goes against everything that we are as human beings.
PS: I have shielded for the best part of the past year. I have seen my partner maybe 5 times, and most recently not since December since we don’t live together. I was told that if I catch COVID I would be unlikely to survive. But I have been vaccinated.
But surviving COVID i no longer enough. What’s the point in surviving if we’re not actually living.
So if after this I happen to catch COVID and die, then so be it. That doesn’t mean that I advocate throwing caution to the wind, but there does have to come a point when we weigh up the risks. Against the achievements we’ve made.
