"Just wait two more weeks"? A request that's become almost cliché during COVID times.
It doesn't actually matter what the disease does after the summer holidays (an arbitrary point given virus lag times). It's not a dangerous disease. There is no justification for it even now, or even at the beginning, knowing what we know today.
My last remaining grandparent is far more at risk from being left alone for long periods, than COVID. Deaths from poor or non-existent care in care homes due to lockdowns are certainly a contributor to excess deaths e.g. in Spain where panicked care home staff abandoned the elderly to die:
The virus isn't dangerous. I understand this is hard to accept given what's happened but the data is uniform and consistent on that. Swiss excess mortality data shows nothing unusual even now the epidemic is over:
In fact Switzerland is now experiencing below average mortality, indicating that some of the people who died with COVID were at the end of their life and going to die in the next couple of months anyway.
Moreover about half of all deaths were in nursing homes, where lockdowns have no effect and certainly masks on ÖV have no effect
Your response is sadly typical of too many people now: running from data, from the truth, and claiming anyone who tells you what really happened must hate their own grandparents. Sorry but it's a shocking and dirty tactic.
