Apparently there are some JW families who are happy to live and let live, knowing what a df would do to them. There are others who want blood; they want justice to be served and to be able to play their little judgment games. It seems you know some people in the second category - bummer man.
Be careful with the lying; if there had been two guys on the doorstep there they'd have their witnesses for your 'loose conduct' DF trial. You might one day have to deny you said that, or you might just not care. Make them work for it, but prepare for the possible eventuality that you'll be DF'd for some ridiculous charge. It looks like it won't make any difference with regards to how your family treat you, as it seems they've all Marked you anyway, and it doesn't seem like it will be any great loss. It might even make it easier for your kids to understand why their family shuns you now.
