Your raise an interesting point Jeffro. An analogy is an process where we take meaning from one subject and transfer it to another, i.e, “The human brian is like a computer.”
She’s trying to make a comparison between being unvaccinated ( As the “expert” she should make the distinction between whether or not she is speaking of persons who have natural immunity or persons who have never come in contact with Covid-19, the latter being virtually impossible at this point ) and being a drunk driver which is a completely false and irresponsible thing to say, especially when given the platform to reach millions of people.
There is no similarity between the two subjects so as to make an analogy. There is simply the appearance of similarity, much like the JW/Baptism/License comparison which is also false.
“That sound is like nails on a blackboard .” Is a metaphor. The sound could be very different from the actual sound of nails on a blackboard, but the reader has to understand the meaning of the metaphor and recognize that the “sound” is not analogous to nails on a blackboard.
“It's just a metaphor for quickly comparing ideas. Most readers with a fairly basic education would understand the intent of the comparison the doctor was making.”
Sadly, the “intent” of the comparison is to make “most readers”, listeners in this case, believe that the “sound” is actually “nails on a blackboard” when it isn’t. She wants the public to view unvaccinated people as they would drunk drivers. That is completely false and irresponsible because one is not like other at all. The subject is far too nuanced, but that doesn’t matter as the “News” simply wants shock value to influence the fairly basically educated public.
This “fairly basic education” you mention doesn’t seem to exist given that fact that many, many people are swallowing the bait, hook, line and sinker.
“Analogies prove nothing, that is true, but they can make one feel more at home.”
