Well, disingenuous questions are usually meant to derail the topic at hand by forcing you to address a topic you haven’t prepared for. In such cases, I would put the burden of explaination on the person who asked, perhaps with some equally unanswerable questions.
“What about them? Do you expect they will be able to farm better in a desert? Is helping them through climate change initiatives more difficult than surviving climate catastrophe?” etc. etc. ad neaseaum.
But it’s still daytime…
Are you from the future?
