Okay, I can see the sense in that. I just wouldn't want this sort of agreement to devolve into a kind of communally-imposed censorship of certain topics 'for the cause of Reason', in the same way that many evolutionists (theistic and atheistic) keep telling anti-theists to shut up 'for the cause of Evolution'.

In other words, I'm all for restraint if the goal is to focus on rationality, but I'm against it if the goal is to avoid offending people and preserve harmony.
