Continuing to repeat the same inane statement that death is part of life means nothing. The issue is whether the death is preventable. Under your thinking why should we cure early cancer cases? They are only going to die anyway, sometime. We are all terminal under your theory. A facetious argument.
The Vietnam analogy is particularly apt cause it was a completely unnecessary war. All of those other cause of death were around back then also. But the war dead was an unnecessary addition to those as is the amount of the toll here. It also took over 10 years to kill that many. This happened in 9 months.
COVID is also hardly an amateur pandemic. it’s likely to kill between 400-500 million Americans in 18 months. There are also the hundred of thousands who were seriously ill with it requiring hospitalization. The long term consequences for those remain to be determined.Other than 1918-1920, there has been nothing like it. There were also many restrictions and mandates put on the population back then including quarantines and masking requirements. Where those steps weren’t taken there were more dead. It wasn’t just a race to herd immunity, and your post is dishonest for suggesting it.
Finally, society isn’t shut down. It’s limping along until we get a vaccine as it would be without restrictions. What can’t you do now other than not go to mass gatherings, and in some places not dine in or drink in at bars and restaurants? Other than that, you can pretty much do what you want and be as stupid as you want to be. Many are taking full advantage. Many jurisdictions don’t even have mask mandates. The prez is throwing a NYE party for over 500 people. Some shut down snowflake. You even have a bowl season and CFP to enjoy.
In short, you are full of shit. That’s not ad hominem, but rather the truth.
