Luke 12:53
They will be divided, father against son and son against father, mother against daughter and daughter against mother, mother-in-law against daughter-in-law and daughter-in-law against mother-in-law."
This verse speaks of non-believing family being against believers in Christ. The division is over Christ. I can not think of one single instance that a JW has been persecuted by anyone, let alone a family member in the name of Christ. I can think of countless examples of a nonJW (or a exiting or questioning JW) being turned on by their JW family for questioning the WT. I can also think of cases of the JW family turning on one for their beleifs in Jesus.
