I'm assuredly not a medical professional, but I am a well-read amateur and an actually mentally ill person. Some of the statements I read in "why do they believe that way?" threads are ridiculously ill-informed and paint me with a brush they certainly never intended to. I get furious when I read people talking about being afraid of the mentally ill; we're more likely to be victims of violent crime than perpetrators of it, and when we are perpetrators, our victims are usually other mentally ill people. But I have yet to read a thread discussing mental illness that doesn't caution people to be careful around "those people."
