OK, let me propose a clarification of the words we are using for this discussion:

• politeness - adhering to a set of widely accepted social norms of communication

• being civil - avoiding showing strongly negative emotions, or directly acting to produce such emotions in other people (in most societies, is a part of politeness)

• niceness - having positive emotions directed at other people, together with the caring and pleasant behaviour that naturally result from it

So, using the above: LW is not big on politeness, and I fully support this position; LW has being civil in its established norms, and I suggest we keep it; LW norms have nothing on niceness, and I suggest we work to change this.
