here's the thing about telling people to CW things:
1. CWs literally, logically cannot be a one-size-fits-all, universal norm. Humans are not limited to needing warnings for "predictable" subjects, or any small/reasonable set of things, at all. any aspect of a traumatic memory can become retraumatizing; my go-to example is someone who pointed out they're triggered by schoolbuses. should everyone, everywhere CW photos of schoolbuses? I don't think so! it's impractical, and how are the vast majority of people supposed to figure out that's a thing?
But if someone in your circles asks you to CW schoolbuses, you can certainly CW schoolbuses. CW conventions CAN be effective when tailored for the needs of a specific community, but this means CW conventions Need to be different between different groups. why?
2. Attempts to be exhaustive about CWs aren't just logically doomed to fail, they're inaccessible.
a. If the rate of CWs is too high, people's ability to make decisions gets overloaded.
