One of my nieces is coming home from institutional psychiatric care today. She was committed due to experiencing 'command hallucinations'. Her parents lean to the right and lean fundamentalist...but they didn't jump to demon possession as their go-to explanation for their child's problems. They sought professional medical help, got drugs for her that eliminated the hallucinations (until recently, she's still a teenager and her meds will have to be adjusted periodically). I had no input on this except for giving what advice I knew to give when asked, I'm just the uncle. Their beliefs are their business. But I'm glad they didn't make their child's situation all about their religion.
I'm not anti-Christian. I'm anti-stupid.
