They stopped using that word because it wasn’t descriptive. The same reason they stopped diagnosing women as “hysterical”. That’s the cool thing about the sciences; they evolve and change over time to be more descriptive, not less.

And now, we use the word hysterical to describe certain things…kinda cool how that works, right? When I call something hysterical (extremely funny) - people don’t get offended and say I’m using a slur.

Or when someone is losing their shit, you say they’re acting hysterical. It’s become a descriptor.
