You should've raised your hand to give a comment and started reading the scripture about the lack of natural affection in the world being a sign of the end then said "wait, I think I'm on the wrong page..." and just given the mic back.
Current new light, as far as I know, is that it's good for Witnesses to privately grieve and to pray for their Disfellowshipped family members as long as they aren't flagrant apostates.
Also, publications say that Jehovah grieves for Disfellowshipped prodigals and He desires they return to Him.
False. There was a recent WT (think it was November 2014) where they essentially likened DF'd ones to people who were killed by Jehovah in the OT and their families were ordered not to grieve their loss. Of course they don't come right out and say it, but it's heavily implied that DF'd ones should not be missed. This is just another part of the E in BITE (and in some ways the T) - they're trying to control the emotions of their followers to keep their control in place.
