Well the friend I mentioned in the OP has been dfd for a couple years now but last time we met he still felt it was the truth but couldn't live up to it. Needless to say I helped him see the error of his ways and enlightened him on a few truths about 'the truth' lol. He sees things very differently now.
I wanted to show him the FAQ on shunning so he could perhaps show his parents (who shun him until they want/need something from him).
I was hoping he could find some way to reconnect using their own words against them... It seems I'm a little late :(
