I just wanted to let you know, that these 37 rules are really, really hard at first. Especially when they speak complete irrationality and your first instinct is to call them on it. That's what I did. I still have no regrets in how I handled myself because I did the best with what I could at the time. You seem to be an assertive person that will call it like it is ( as am I as well) which is an awesome trait. However it doesn't matter if you're God himself, there is no reasoning with the MLCer, when they're in the throws of replay. Think of this as something to save your sanity, first and foremost.
Even though what they say is unreal, untrue, and insane, just stepping back and not getting engaged into what they're saying/projecting/and accusing you of in the long run is the best way to protect ourselves and our sanity. Just don't partake in it to save yourself. Now Im the first one to stomp my foot and say that's so much easier said than done. Oh it's hard. There will still be backslides, and like I said, sometimes they're necessary. But getting into the tit for tatt crap with them is just the time to be quiet and don't go there.
However if you find yourself in the sitch that some sort of response is needed or appropriate, especially if spew is coming in droves, I would suggest objective statements or questions to redirect where all this is coming from and/or active listening. For example:
Why are you acting this way? Why are you so angry? What makes you feel that way?
So if I hear you correctly, what I hear you saying is : (fill in the blank).
Either they'll be so stumped they can't speak or just come up with more spew and get worse.
