Ultimately this is not a discussion forum, it's a question and answer site. Comments are (and were always) meant to be a temporary artifact, used to request/add additional details.
When comments are flagged as offensive; as this one was, it's common practice to remove the comment. This is especially true if the comment is deemed to actually be offensive by the moderator that reacts to the flag. In my opinion, it sounded as if the user getterdun was saying this was a stupid question to ask. And by extension, calling the asker stupid themselves for asking it.
Common sense should have prevailed, and this question should not even have been asked here: -1.
Remember there are no stupid questions.
If you feel a question is off topic
- Raise a flag.
- Post a question here on Meta.
- Ask about it in chat, if you want a deeper discussion.
Civility is required at all times; rudeness will not be tolerated. Treat others with the same respect you’d want them to treat you because we’re all here to learn, together. Be tolerant of others who may not know everything you know, and bring your sense of humor.
Please note that expletives are not allowed. If you use expletives on this site, you may be issued a warning or a suspension.
When shouldn't I comment?
Comments are not recommended for any of the following:
Criticisms which do not add anything constructive ("-1, see previous comments you scallywag!"); instead, down-vote (and provide or up-vote a better answer if appropriate);
Discussion of community behavior or site policies; please use meta instead.
