Disfellowshipped persons (for whatever reason) are marked for death at Armageddon.
JW's are NOT to even pray for them.
They are not to eat a meal with them or even speak a greeting to them.
If this does not qualify as demonstrating HATE I can't imagine what standard you are holding!
Mother's no longer speak to their grown children. Families turn their back on each other specifically because they are TOLD TO DO SO.
I know a mother who was disfellowshipped when she reported the Elders in her congregation to Child Protective Services when her daughter was raped and they were protecting the rapist and revealing unsavory details gained in confidential sessions. For her actions she was considered an enemy of Jehovah. If this isn't HATE I don't know what to tell you!
A JW parent that would go against the recommendation of qualified physicians for medical treatment are "hating" their child
in AT LEAST the same way the bible uses the word hate. "The one hating is son is witholding the rod of discipline."
Witholding a blood transfusion falls into the category of deliberate act leading to dire consequences.
