If anyone says that you are a horrible person for how a character acts, @Lithium, they may or may not be complete jerks. They probably are jerks because they don't care to share the same game goal as you do. The unwillingness to cooperate and negotiate are jerk actions.
Or as Gany says, maybe you're the jerk because you're motivated in a way that attacks someone else's play. (I'm not accusing you of this, I'm just saying again that she gets it.)
Goals, theme, setting, character, NPC, environment, these are all tools. When we talk about "IC" we should be talking not about a tool or an action, but the context in which we see our actions and these tools applied.
The tool can be applied to tell a story, or the tool can be applied to fuck with someone else's telling of a story, but it's still just a tool.
The problem with talking about "IC/OOC Separation" is that has become misleading as to the nature of these tools, and that's something you've ignored me saying (for reasons I literally cannot understand don't understand). The term is now a label, and practically a cliche, that does not help our hobby one bit.
Maybe, some day, we can excise it from our vocabulary because we can better understand our relationship between ourselves and the IC framework. IC is not apart from OOC, it is a subset of OOC.
