CHG, My concern is this. You mentioned that you had to get a cease-and-desist order against the elders who were hounding you.
By your going to their KH, would you be nullifying that c&d order? Would the elders perceive it as a nullification?
If so, that means that they will feel that they can pester you again, and you'll have opened a can of worms.
Edited to add: Actually, by your setting foot in their KH, you are giving them the 'right' to have a 'backroom talk' with you. You are 'associating' with other JWs, and they may feel that you are trying to influence some... and they won't stand for that.
Kinda risky if you ask me.
What I would do if put in similar circumstances (and did for my ex-father-in-law - who passed on, and they held a memorial at the KH), would be to show up prior to the services, sign the book, view the deceased, show respect to the family and friends... then leave prior to the first words spoken from the platform.
Of course, you may not be able to do that if you are there for moral support for your mom or someone else.
Just my .02 worth.
