I don't think the argument is to not care how society works at all. But if people are caring so much that it's making them act in irrational and harmful(both to themselves and others) ways maybe we/they need to dial it back a bit for both our/their and society's good. It's not at all clear that this "culture of outrage" is having a positive impact in how society works, and if it isn't maybe we need to stop.
