I've enabled comment moderation this afternoon just to make this work. Don't worry, it won't last. I hate comment moderation, too.

If you want to respond anonymously, which is fine, please do mention in the comment whether you work in religion, politics or neither.
If you don't know, I'd appreciate it if you would comment "I don't know."
