I believe that in our modern age of supposed reason, certain biases from the old way of doing things remain. Perhaps they are human nature, or perhaps they are simply the result of our post-roman culture. But either way, there is a massive tendency within our society for people to expect doctors to do ALL the jobs that priests and witch hunters once did. We no longer believe that autism is caused by the fey stealing babies, and we do not believe in possession by evil spirits either. We believe in scientific medicine instead. But for some reason, we expect scientific medicine to let us act exactly the same as those old myths. We want to believe that mental disorders from the DSM possess people with the spirit of evil and justify lynchings. We want to believe that people with NPD are essentially vampires - inhuman, predatory, corrupted by unforgivable sin. We want to believe that science and medicine can show us wickedness and sin, and tell us who to kill for being different. Superstition didn’t go away, it just changed its face.
