I know Kitten. They're good people. I hate seeing hateful, stupid comments like that about people I know. It's dehumanizing. If I saw one of my friends posting it from a conservative site, you betcha I'd be really vocal about it.
InformingLee: Yes, Kitten and Brynn are legally married. Kitten was raised in a Christian background. Doll is Pagan, and she didn't really care about the legal documents anyway; however, they did have their lawyer draw up legal documents regarding their wills, living arrangements, separation, etc. Also, insurance factored into the decision about the legal marriage arrangement, because Kitten wanted to have a baby.
They don't mind answering questions about their arrangement at all. If you want to see a better article, try the one on Offbeat Bride.
