Not sure how long you've been studying or how long/what kind of a friendship you have with your "mentor".
But if you really want to see the true face of JWs ask the question below and take a big step back.
"You know those nutters that make the news saying things like 'the world will end this week'?
"Yes"
"Well when it doesn't happen do they become false prophets like Jesus said?"
"er . . .yes"
"Is it true that for at least 60 years up until 1995, JWs preached that God had revealed through the WT that the generation of 1914 would see paradise restored?
" . . . er . . . (shuffle, shuffle) . . . (attempt to change subject) . . . er . . . what have you been reading/who've you been speaking to . . . ?
"Well is it true?
" . . . well yes . . . but . . . "
"Ok come back and see me in 7 years (2014) and apologise for personally spreading false prophesy. Then I'll tell you what I've been reading/who I've been speaking to.
If you didn't know the above maybe you should check out what you are getting into.
Seriously - do your research. And welcome.
