I try to bring up the DF'ing and Worldy Association doctrines with my mother. Deep down I know she hates both policies and chalks them up to "imperect men."
Name some "worldly" people that she has great affection for, and ask her why Jehovah is going to soon destroy them and their kids.
Regarding DF'ing, ask her what purpose it serves to DF an unmarried woman who accidentally gets pregnant. What support group does this leave for the young lady who will soon be a single mother with tons of guilt, etc?
