Over quoting, but a lot going on here.
Let's start by saying it is pretty obvious that people who aren't vaccinated carry a higher risk of death or complications, all other things being equal.
However, the point about hundreds of thousands avoiding the vaccine and choosing death is a bit harder to prove, since so many died of (or with) covid19 before vaccines were available. Especially in the 65+ age group. So, it's also suspect to try to use their high vaccination rates NOW as any kind of argument about effectiveness THEN, when it wasn't an option.
I think jahsoul could have done a better job explaining their point. It was incredibly ambiguous. If the point is that now, over 55 years of age has the highest overall vaccination rates, and younger folks tend to be lower, and under 55 age group hasn't had hundreds of thousands of confirmed covid19 deaths... ok, sure. Many people still refusing may be in an age cohort where the risk is low to them. But many age groups are hovering in the 10+% of total deaths range. Younger is still like 6-7%? (In my head, I should actually calculate it).
