Zero, like some of the other pre-Internet people out there.
My BS meter pinged every single time I was with a brother or sister. Mostly the brothers, though. Plastic smiles and forced happiness. Bible studies where nothing was questioned and nothing made sense. Being chastized for even thinking about going to college. My turning point was the blood doctrine. Reading celebratory accounts of Brother and Sister X losing a child because they withheld a blood transfusion utterly disgusted me. I realized that if I had a child, and that child needed blood to survive, I'd be in the next room rolling up my sleeve before you could say "Armageddon".
The Internet has been invaluable as my wife and children have no idea what I went through as a Witness. I've enjoyed (virtually) meeting several of you as you 'get' a part of me no one else in my current life does. I'm glad my family doesn't know even half of what I was like back then.
