I think they are definitely mentally ill, but not necessarily mentally unstable. On the contrary, they come off to me as extremely locked into their delusions, fixed and rigid in their thinking. Unlike people I know with other mental illnesses, who tend to have unstable, changeable moods and thinking and experience a lot of self-doubt.

Trans people are different from lots of other mentally ill people coz their mental illness has caused them to join a cult and adopt a very rigid, black-and-white way of thinking and world view. Which lots of mentally ill people don't do.

I find TRAs and trans ideologues to be almost zombie-like and unable to see things from anyone else's point of view or to consider even for a moment whether they might be wrong. Whereas most of the people I know and have known with mental illness are still able to have empathy and sympathy, they are capable of seeing that their POV is just their POV, and aware that what they believe to be absolutely true might actually be a misperception or delusion. Whereas TRAs and trans people are 1000% wedded to their delusions and misperceptions and totally convinced that they are not delusional.
