Moderator Keen mentioned that I used "racial code words" in some of my questions, and linked to this wikipedia article: http://en.wikipedia.org/wiki/Dog_whistle_politics
While I am obviously familiar with racial slurs (n-word, c-word, d-word, etc), this is the first time I've heard of code words... and the article DOES NOT LIST these. I asked some of my coworkers if they were familiar with "racial code words", and they haven't heard of them either.
Is there a list of "racial code words" we cannot use here? Or should I just avoid asking questions about negative actions/situations/characteristics of non-white characters?
