Yesterday I wrote on what I see as changes through our/my history of what is "canceled" and what is not.
I've a metaphor:
Think of society in history as being reduced to a map in some way. Then the boundaries of what's included and what's not can be represented by a low resolution magnifying glass help over the map, a glass which brings some aspects to the fore and doesn't recognize other aspects. But over time the glass moves around, adding and subtracting things to look at.
