Well, good news that your friend is really willing to consider the evidence. Anyone I know?
If she is more concerned on things that affect peoples lives, how about the changing teachings on organ transplants and what parts of blood are blood? Another one is the rape / fornication / must scream / mustn't scream saga. You only need to show her the WTBTS own literature for that - no "apostate" literature required.
Pehaps one could shove a flashlight up their butt. Sorry I'm still mad about that man that killed his kid, hey there's a good one to share with anyone who is wondering about whether to stay in the org.
