Exactly, spuki. She was one of us, not too long ago.
According to the article, she was once institionalized as a teen. Now, she grew up in a conservative area in a religious family, so it could have been a bs move to get rid of her lesbian tendencies, or she could have been genuinely messed up.
When I heard her voice go all hissing, vicious and crazy sounding in one section of the audio of the SF gig, I knew she was sick. I think she is in fact gay, is trapped in a hetero marriage that makes no natural sense for her, and has been brainwashed by her church, and has now snapped.
I have no idea why she would have ever gotten into extreme Christianity, unless she had some bad mental episode in the first place.
