Speak up against what? It's an unfalsifiable immeasurable diagnosis. I appreciate that most everyone means well, but academia is not some city on a hill with saints wielding an omniscient peer review process. Incredibly elementary statistical errors make it thru peer review process in even the highest impact journals somewhat frequently - so no I don't have any faith that academics would criticize an unfalsifiable diagnosis even if they could. That's really the basis of my opinion in the first place - if you can't prove something is true then you can't prove it's false. That being the case, what's the point of the label to begin with?
