I see where you are coming from, but I do think the fact that someone has an official position as a moderator tends to modify their behavior, and that they do have a tendency to accept a collective responsibility.
Lightening McQueen for example (an ex moderator) has made comments about enjoying the freedom to express opinions regarding certain vendors now that hes "on the other side". That kind of implies that quite understandably, there's something of an us and them culture. How can there not be ?
Only yesterday Counter Violent made a comment about giving up his moderator position should a particular ex member be reinstated, in order to participate in what might be described as "a full and frank exchange of views". It seams to me that he would NOT be comfortable engaging in that type of debate as a moderator.
I do think that occasionally views that are expressed publicly and privately do differ, but then again, that probably applies to all of us at one time or another.
