Again I have to agree with Ding. Try not to say negative things about the religion---don't tickle the "persecution" trigger. They have already told her eveything an opposer may say to her, and if you play into that it could, in a sense, prove that all they are saying is true. After all, they were able to predict how non-believers would react, and therefore may know how satan is working.
It's kind of like when your friend is mad at a boyfriend or husband. You listen, you're supportive, you offer comfort, but you try not to say anything bad about the other person. Because remember, if she does go the other way and chooses to go back *cringe* you don't want to have that between you because the wall will be thicker against any future attempts by you to lure her away.
