More substantively, I don’t think the problem is one of outrage, or outrage culture. After all, you seem fairly outraged at Tuvalu’s treatment yourself. Instead, the issue seems to be what people do or don’t do with their outrage. It used to be that people used their outrage to write responses and critiques of those they were outraged at. Nowadays, people seek the removal of whatever caused their outrage. You see this here but also in campus culture more generally. From what I can tell, this is reflects a generational difference; millennials seem to want anything that disturbs or outrages them to cease to exist, and some non-millennial professors pander to this, wanting to be seen as woke or something. It’s all very troubling and ultimately antithetical to the philosophic enterprise.
