What are the guidelines for flagging questions/answers as offensive on mi yodeya? Often, there are postings that ironically ask about halachic applicability of e.g. the principle of mishum eiva, which themselves seem to be violations of that principle, posting content that could easily be misconstrued/misused as offensive to non-Jews. Perhaps some of the back-and-forths are more appropriate for more private forums...
I think you need to use common sense to determine what is acceptable to post and what is better discussed elsewhere.
Posters need to be cognizant that their posts are read by a wide variety of people, Jews and non-Jews in various places with various perspectives.
People need to exercise responsibility and prudence in everything published online or in any open forum.
אבטליון אומר, חכמים, היזהרו בדבריכם--שמא תחובו חובת גלות, ותגלו למקום המים הרעים, וישתו התלמידים הבאים אחריכם וימותו, ונמצא שם שמיים מתחלל
Avos 1:11 tells the scholar to be careful with his words, lest they result in a Chillul Hashem.
