What subjects are taboo on Fluther?

I asked this question almost exactly a year ago using different wording.

I cannot speak for anyone else, but I find that I self-edit sometimes on Fluther. I don’t ask questions about some subjects—spirituality for one—because they have been roundly condemned in the past. Like most members, I avoid questions that I have no knowledge of and questions that I simply don’t want to engage in. For example, I very rarely answer questions marked NSFW.

I’m curious. Am I alone? Do other members here leave some subjects alone for various reasons? If so, why?

Are some subjects simply taboo? Are there questions that are off limits for Fluther?
