Thanks for asking this question. I was about to open up a meta thread on the same topic. I flagged the cited answer as offensive, and I commented:
I have flagged this answer as "offensive / abusive". I did not do this because of the use of words like "damn" and "asshole": these do not offend me (and do not offend most adults I know). Rather it is because the answer explicitly advocates that a teacher hate a student. As a former student and current teacher, I am certainly offended by this, and I hope others agree.
Professor Ismail responded with the following comment:
@PeteL.Clark: The correct way to express violent disagreement with an answer is to downvote it, not to flag it as offensive. I also find the thoughts expressed repugnant, but I am quite sure you can find many faculty members who are cavalier to the whole concept of mentoring.
This confuses me. As indicated, I did find the answer offensive. The text for this flag reads:
it is offensive, abusive, or hate speech This answer contains content that a reasonable person would deem inappropriate for respectful discourse.
This is a faithful description of my feelings about the answer. (I am making the implicit assumption that I am "a reasonable person". If I am mistaken in that, please do let me know!) This leaves me confused at the transaction. It might be that the moderator in question simply does not agree that the answer is offensive -- reasonable people can, and do, disagree -- in which case I understand why the flag was declined but not the comment: just because a flag is declined does not make it not "correct". However, the comment also expresses repugnance. It is my understanding that "repugnant" is a synonym for "offensive", so given that Prof. Ismail feels this way, I am confused not only by his explanation but by his declining of the flag.
Added: As one might have guessed from the comments above: no, I do not feel the need for a "no nonsense you curse you get warned policy". No academic I know includes "curse words" in their writing without a good reason. But some academics do include curse words in their writing (I have done it on occasion). The syllogism ends: we have good reasons for doing so. An outright ban thus seems "unacademic" to me.
