I am truly sorry to hear that happened to your brother, Newly Enlightened, but what happened is not relevent to the statement that was made.
Just because an individual chooses to go beyond the WT's rules by shunning a non-believer who was never baptised, doesn't make their behaviour official bOrg policy and non-adherance a DFing offense. Any JW who knows how to defend their cult will know that, and use it against you.
I've never been baptised and I've never been shunned. I have never been DF or DA, I'm not gay, I'm never seen in a KH except at funerals & weddings, and I don't ride a bicycle. Please show me an article that clearly demonstrates that my parents should be DFd for associating with me? That is what a JW defending their cult should ask you to do, especially if they are trying not to lose a potential convert.
JW's permit themselves to lie and cheat in defense of the bOrg, but we have to be seen to be better than that. The bOrg portrays us as liars, they in turn, portray us as liars to their new recruits and they will use any mistake we make to polish their image and trash ours, so we have to be squeeky clean when we make statements. If you make ten correct assertions and one wrong one, which one will they want to talk about with their 'student'?
