I must say I never did, probably because of my upbringing, my parents were unusual as JW's, not judgemental, kind, and understanding of people. I felt pity that the "worldly" people that could not see "the truth" and therefore would find it impossible to build the faith I thought I had, but never did I feel contempt for them.
Truth to tell, the embarrassing thing (embarrasses me now) I did feel sometimes, was a slight feeling of privilege, that these "truths" had been revealed to me, but I still respected "worldly" people, and, strangely, I felt more comfortable with them than with JW's............. I wonder why ?
