I asked an older JW sister who is very in, but anti DFing and shunning, what she would think if they introduced tithing... She said "We would have become a part of Christendom" she then called her husband 75 year old to see his thoughts and he said it won't happen, ' that's what false religion does, not us'
maybe that's what will rock older people's boats...tithing...because it's 'what the world does'
