Yes, they are making this up.

From the point of view of a person without ADHD, an ADHD person is almost retarded. Can’t concentrate, achieve goals.

Or BAD - jumping from a depression to a psychosis, sometimes they are like a wounded deer hiding in their room, sometimes they are running around planning to blitzkrieg the planet, what is this if not a defect. (There’s one woman, I wonder if I should reach her or if I’m having my own BAD psychosis even thinking about that. She’s also not the only woman who can be affected strongly by that decision. In other words, I’m inadequate and unable to control myself and clearly see the reality behind impulses.)

Or, well, an autistic person struggling with hints and cues and aesopean language and unable to deduct reality from superficial signs, - from the point of view of those who can they are pretty much defective. (Also me.)

They are just bunching together a few of Ds as “just different” and the rest as defects. “Disorder” is not a word meaning “just different”. It does mean a defect.
