This is my tactic as well. I'm in New England and a coworker was once distraught that someone dismantled a statue in the south. I asked if they had any idea that the statue existed beforehand? They did not.

I found out about many of the artifacts for the first time in [1] after they were destroyed and was still upset by it.
Your question does not adequately reflect why someone should or should not care about something.

Eg someone's frustrated with some problem they're facing, to shift their attention from that they instead start ranting about an irrelevant problem elsewhere in the world. Then you go and shut them down by asking them why they care.
It's important to recognize that their anger being irrelevant towards the issue also means that there isn't much lost by letting them vent.
