During a rather belated, hasty and ennuyed reading of the recent "atheism" thread, I observed several mentions of the "NCNC rule". Really the NCNC 'rule' is less a rule than an emergent understanding that discussion of real-world religion and politics tends to lead to situations arising in which something someone says upsets someone else. IOW, it's a rule of thumb about how to avoid upsetting some fellow listmembers. Contrast this with the 'law' that says that auxlang advocacy shall be banished from Conlang List to Auxlang List, which, IMO, is more fully part of the constitution of Conlang List. The impropriety of engaging in auxlang advocacy on Conlang List is the impropriety of flouting a quasi-constitutional law of the List. In contrast, any impropriety of engaging in discussion of real-world religion and politics resides not in the breach of any quasi-constitutional law but only in the general sin of offtopicness and in whatever impropriety there is to speech that brings about others' distress. --And.
