"moral indignation" is timeless. But it does feel uniquely current to have two political parties that seem to use it as their primary currency (in the US at least). I have trouble recalling any major legislation after the Affordable Care Act that wasn't fully grounded in moral indignation or virtue signalling.

Well, the age of enlightenment was well over a century and people seem to like moral indignation and outrage more, so I'd guess we're gonna stick with it for a while.

> at what point do we stop calling it an "age"?

Pessimistically? How long did the Bronze Age last?

from about 2000 to 2015 we were relatively free of moral puritans trying to censor people, language, art.

but now it has returned with a vengeance and even worse than the moral panics of the 80s and 90s.

It definitely wasn't like this in the late 90's / early 2000's.
