Hi WTT, I wish you luck buddy, some close family members and I are faders, and I know exactly what you mean, it is really hard to keep shut about what we know, especially if you have really zealous family members whose every other word is Jehovah - If Jehovah allows, thanks to Jehovah etc, UGHHH - it can get irritating.
I've already stuck my foot in my mouth on occasion, so be very careful, just think to yourself "Theocratic warfare strategy" and you will be ok.
