EDIT: also it's still fair enough to be critical about these things. schizophrenia is no 'excuse' in that sense.
I'm not defending said theories at all, just saying that my experience with schizophrenics is that they are very much influenced by the topics that are relevant in their surroundings.
It's easy to empathize with the mentally ill as long as they don't personally affect you and/or your high horses.
Terry Davis, the late schizophrenic author of TempleOS, had a number of racist rants and other bigoted and hate-filled videos on YouTube.
This is the biggest straw man argument I've heard today.
Research and clinical communities can better determine whether some classification occurs frequently with some symptom. Or were your HN comments meant to further those efforts?
