You’re very wrong in your statement, “...at its worst is just a severe common cold.” I’m not going to go through arguing it again, but I’ve previously posted on this forum that this virus does badly injure young people, and on occasion kills them. I’ve posted direct reports from physicians in my family, but the FluBros here refuse to hear anything that opposes their narrative.
You are right, though, that if you are young, most likely you will not get seriously ill. However, some will, and will end up in the hospital on O2 and possibly the ICU. It’s a dangerous virus.
Re: “COVID-19 does badly injure young people, and on occasion kills them.”
I agree.
But seasonal influenza and common colds also kill hundreds and disable thousands of completely healthy Americans each year.
Do you really want to shut down the USA for six months every year to protect them?
Sorry - that is insane, that is deliberate economic suicide to protect a tiny fraction of one percent of our population.
