[WikiEN-l] Strange and unfair RfC/user process

[actionforum at comcast.net]

I received a notice of an RfC/user against me.  So I went, read it, and started to respond, noting some false charges.  Some of the editors claimed to right to talk out those false charges, after I had responded to them.  Changing the statement of dispute right from under my response and under each others signatures.   It seems to me that is vandalism as it is a violation of wikipedia integrity and changing signed comments.  Their changes in meaning have implications for my writing.
They appear intent on continuing, and nothing has happened on my report of severe vandalism due to the changing of meaning.  
If the process really works this way, it seems unfair, as if I am just refining their charges.  They can try out ones that they would like to make, and then, if I do the research and refute it, they can just withdraw it and try another one.
Is there a place where more specific rules have been defined which address this issue?
