In some cases, references to bigoted activity are essential to the question itself:
However, I saw a question today from IPS that made me wonder about how we can best follow community guidelines across the site. This question includes a flippant reference to pornography use.
The line is irrelevant and will likely be edited out soon to avoid distracting from the question. That isn't relevant to this question, which is largely theoretical. What I am asking is specifically about non-essential lines or comments referencing discriminatory or harmful activity against certain groups. Is that against the CoC?
