I imagine somebody has already coined "outrage fatigue."

About 10,000 times according to a couple of search engines, yeah. *wry smile*

After all (says a very guilty party here) they are so much easier than outrage and compassion.

Or, to quote Spider Robinson, "Hope costs. Once you concede that problems can be solved, you have to get up off your ass. Despair, by contrast, is cheap, self-powering, eliminates unwanted guilt, and requires - permits - no effort."
