Welcome to the forum, cherrypye.
What I have done, is to bone up on the literature of the era when my parents joined. They were not entirely honest with me when I was growing up. When they try pressurising me, I pick on stuff that I know they know. Stuff that they were studying right at the beginning when they were new recruits, all fired up and wolfing down every piece of noo lite Judge Rubberass & co were spewing. Stuff that they would rather forget, but cannot deny as they have the rags on their own bookshelves, and especially out of date apocalyptic doomsday nonsense that they expounded to me.
I remind them that, as a child, I had no choice but to believe whatever they did and quote, verbatim, my father's rules. I'm not a kid any more, and I do not believe that I am required to join their church, so if they want to conscript me, they are going to have to start from scratch and answer the questions that they put psychological pressure on me not to ask as a child. They now have one question to answer, and they get reminded of it every time they mention religion. If they are foolish enough to ask a question, I ignor it and ask them why they haven't answered mine.
I have made it very clear that I do not believe they have any moral high ground, and that every standard that they hold anybody else to, will be used by me to slap them around the ears with should they attempt to break one.
