My thought exactly billy.
I was thinking, if you're still in school, to bring it up as another "peer” was asking questions and THEY looked up the info. Now you have the upper hand because you were trying to show him/her the “truth” (like a good little drone), got stumped (oh help me mommy and daddy) and have a legitimate reason for asking and trying to get answers.
For this to work though you need to set up the situation, your parents must be primed about the "peer". They need to know he/she is not open to an at home visit, will only speak to you at school and is smart so your reply has got to be concrete and truthful because he/she will check it out. Try to use a real peer in case this goes sour, you may need a "fall guy" (but be sure it's someone who is willing and knows what's going on or someone you know hates the JWs and would gladly say they looked up the apostate stuff). What’s the worst that could happen, your parents tell you not to associate with this person anymore? If it’s someone you don’t associate with, only do things with at school or talk to in secret anyway, all you have to do from that point on is say you've stopped association and keep on doing what you've been doing; you'll be a little bit smarter and your parents will be able to stay in ignorant bliss.
If you want to get cocky, and your parent’s can’t/don’t want to answer your questions or get pushy, turn it on them. Ask why they can’t/don’t want to answer and/or are avoiding the subject? Say something like, “aren’t we always supposed to be ready to defend our faith to those asking like the bible says?”
