Coming from you Matt, it's not too crude.
I was at the DMV yesterday and over heard this guy telling his friend about how he's been studying with the JWs and learned God's name. I interrupted of course (you know me) and told him to make sure he researched what they tell him, outside of their literature. I also told him that in the beginning they seem wonderful, but the deeper you become involved, teh uglier this can become. I told him 'take it from I me. I was a JW for 19 years, and used to conduct bible study similar to you conductor.'
