There's some harrowing stuff in there, but this is almost so ubiquitous I really feel it's the root of a lot of harm:
"A therapist describes talking to parents after they meet with a medical doctor.
“I would go in, and say, ‘Okay, so tell me what you learned.’ They would be like, ‘We have no idea what they were talking about.’"
Literally not knowing what people mean when they use the words they do is really harmful.
We've seen it daily over the years. "Ok, you don't want to define it, but when you use this term, what do you understand it to mean?" is constantly ignored. It's even on this thread - what did you understand by this? -go ask the author.
Just words being passed around like a meme with no care about what it means in the real world.
