There is a lot of heat (understandably) in this thread. But in my opinion there is also a lot of light. It is sometimes difficult to talk about topics when they are so charged.
But if we can take away the charge and maybe a few things said in the heat of the moment I am not so sure what is conflicted about what MBIB is trying to say. I am also in the camp that sees a lot of the MLC process as a psychological fracture, that it has roots in childhood, it is something that is papers over for a long time until it simply is not contained anymore. Or maybe some fundamental psychological coping structure never fully develops, and the weight of an adult life and conflicts and internal pain finally is too much and the entire house falls down.
Disassociation covers many things and is a spectrum, not two points. So it switching, it can be entire personalities or just mood states. I hear what MBIB is saying is that people in MLC change because of these coping mechanism which become rather acute. I agree. I also can hold the idea that it does not absolve them of the CONSEQUENCES of what they are doing. I am sure at some level they all know what they are doing, they are not helpless victims. But I am pretty sure that most of them are not making happy happy choices and twirling their mustaches, otherwise they would not have the shark eyes, the deep pain, the conflict. And the one real giveaway: healthy people making choices do not harm the people they love AND cut off their best support system.
To be clear to have empathy and understanding does not mean saying it is ok, or to take anyone of the hook as it were. We can choose any path we want as MLCers. I, like MBIB, find that holding empathy and understanding has made this much easier for me and has allowed me to heal and move on. Others may find anger helps them heal, unless it becomes toxic in itself. Because anger that remain for periods of time is not healthy for the person who holds it and probably means they are stuck in their pain in some way. This is NOT meant to be an accusation btw.
To me a big part of mental health is connection to reality. Disassociation and switching are indications that reality can not be tolerated, but as coping mechanisms they take away short term pain at the expense of much larger long term damage. The consequences of these are part of the reality that MLCers will have to face. Unfortunately as LBSes we also suffer these consequences although it was not something we instigated. Such is life, it is unfair, but we have to accept what has happened and figure out how to move on.
