I have a particular question that I want to post that deals with somewhat unpleasant concepts. I do not want to rustle any feathers or step on any toes (I learnt my lesson from my question about gender non-conforming magical people in the Potterverse).
So I want to ask here and get a better understanding of what is and is not appropriate. What topics, if any, are considered taboo on the Sci-Fi and Fantasy Stack Exchange?
