I would embrace any of my family or friends that sought me out. I would hold them while they cried and I would assure them that there is a whole universe out there and lots of places to go....baby steps at a time but as many here know, those baby steps often take off running pretty quickly when the scales fall off the eyes. As for the older ones with few years left that would be harder. While I don't believe in a god in the manner that they do, I wouldn't push my views. My spirituality is my own personal thing as it should be (IMO). For the older ones I think I'd just say that God is about love and no loving God would abandon them because of an organization gone bad. If they just continued on with the most important 'commandment' to love and also 'be modest in walking with their God' then that is their most important obligation in this life.
Something like that.....
