I, for one, enjoy teasing out this topic. It's at the heart of a lot of RP issues, and I've had some good discussions about it, including with Cia and Else while the thread here was running, and with Jade Constantine in LM OOC at the beginning of the year when the topic was hot on IGS.
I think one of the reasons it can be difficult to discuss is that the realities are often complex and nuanced. I happen to think that hypocrisy isn't the worst sin there is, and that the areas where we don't necessarily want to be consistent are often the ones that are most interesting.
Those factors mean I'd like to find ways to talk about IC-and-OOC without assuming that the most important thing is to adopt a consistent overall position which will, most likely, always or never deal with certain problem cases. Describe the different sorts of things we'd like our approaches to be able to cope with, but accept that sometimes our responses are conditional, depending on the characters/players/circumstances.
If we do manage to resume the discussion, could we find a way to say "hm, X and Y seem to be inconsistent: how does that work for you?" as a genuine question trying to open up the next stage of things?
