In the sense of those terms which we use while moderating this site, it was all of those things. I could also have added:

"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."

and

"When disagreeing, please reply to the argument instead of calling names. 'That is idiotic; 1 + 1 is 2, not 3' can be shortened to '1 + 1 is 2, not 3." https://news.ycombinator.com/newsguidelines.html
