disanalogy

How not to make analogies:

The Instapundit comments section is all over this one. As many commenters note, a life vest would not have saved most people in the cold waters of the North Atlantic: they'd have died of hypothermia. So much for the protective value of life vests.

I would add that the premise of the "analogy" is flawed: the tacit assumption is that, just as all the Titanic victims are in a deadly situation, all people exposed to COVID are in a deadly situation, and as we're seeing from the low death rates all over the world, this just isn't the case. COVID is deadly for a small slice of the population; freezing water is deadly for all.

Some Instapundit commenters humorously note that the image actually is analogical: life vests for Titanic victims are indeed just as useful as masks are for people in a time of COVID.

However you slice it, the "analogy" is an own-goal.
