I read an excellent explanation about an informal fallacy in a textbook about 20 years ago, but now I can't find it.
It involves people rejecting a proposal to fix one issue because larger, more important issues exist.
For example, if someone argues "the government shouldn't spend money on trying to reduce sexual assault while climate change hangs over our heads threatening to kill more people than are assaulted. We should be working on that, instead."
The fallacy, the textbook explained, was that it assumed the government could only work on one thing at a time. Such a prioritisation might justify spending more resources on the higher severity issue than the lower severity one, but it didn't justify rejecting a proposal that might help the lower severity one.
I see people arguing this fallacious position frequently, and want to have some resources to support me turning that around, but I don't know the name of the fallacy.
Can anyone tell me the name of the fallacy?
