My friend killed herself during lockdown. She had mental health issues but she managed them well with exercise and socializing.
Should I lay her death at your door op? Do you think that is fair? She was in her early twenties.
How about the hoardes of children missing their developmental milestones due to COVID measures? Or the disabled children who were without any kind of support? The children killed by domestic violence? The murder and arrest of women doing things that were perfectly legal in 2019? Happy to take responsibility for that? After all, it was COVID measures that directly caused these issues and more.
As many others have said, what you want is not feasible long-term or supported by the government. It is not fair to ask people struggling with the cost of living crisis or rebuilding their slow businesses after being left out to dry to by the government whilst many were on furlough to stay home and test, losing out financially, so people can feel safer. And it is feel safer, not actually measurably safer.
We now know COVID passes asymptomatically, we know masks don't work, we know elderly people and the vulnerable are vulnerable to it, as they are vulnerable to flu and other seasonal viruses. None of this means we should practically lock down or change our lifestyles as it makes little difference.
Yabu op. COVID is here to stay and is yet another factor you will have to work into your own risk factors, we all die of something and to be quite frank your elderly relative was lucky to have so much time when so many people don't get it.
