I have never understood this argument so I will have to give an example. Nobody is sending anyone to die.
A couple in their 40's has 3 kids. They may be your family, your neighbors or your friends. They may be your best friend's family. Both parents need to work in order to pay for food, education, mortgage, retirement plan etc etc. Most of their expenses are not discretionary and they live from paycheck to paycheck. Would they like to stay home for another year? Sure, but they do not have that luxury, they have to keep on running on that treadmill or the foundation of the family will collapse. They may lose their house, they may not have the money to put one or more kids through college, they may not have money for health insurance and get very ill or worse if they get sick.
From a Covid prospective they are in a low risk category, for them not putting food on the table is potentially a much bigger problem than getting sick from Covid.
A couple in their 70's. Both still healthy and active but in a totally different Covid risk category. Despite their relative good health, you never know, so better be safe than sorry. Is the first family sending them out to get sick? No. Can they stay home? Yes, and they should, and as long as they do it and take all the precautions, they will not get sick. Their decision is not dependent on the first couple, they are in total control of their own health and destiny. If the first family is destroyed, how does the second family benefit? And how is it fair to destroy the first family that does not have a viabile choice for the benefit of the second family that does not gain anything from destroying the younger family?
Folks, let's listen to our hearts, not to the politicians and to the talking heads on TV. Let's have compassion for old and young. We do not have to destroy others in order to save ourselves.
All my grandparents are dead but I have no doubt in my mind what they would have chosen without hesitation if given the choice.
