I'm thinking of this exchange here Finding the best two predictor variables used conjointly, and levels of each - both in the comments on the original question (and now in the edits to the question) and to my answer. Obviously a good approach as individuals is to stay calm and keep away, but how should we act as a community? I'd like to see a clear message that this sort of behavior is not welcome on the site. But having said that the question is clearly within scope and so should not be closed on any of the usual grounds.
Also, I was surprised to find not much discussion on rudeness in the meta, am I maybe looking in the wrong place.
