I couldn't listen to the blather of that J.W beyond about 4 mins. He was typical of today's JW's just ignorant, of the Bible, of their own Religion and Beliefs, and of anything approaching Scholarship.
Back in the day, myself, and another guy I can think of from my old Congregation, would have had a polite and intelligent conversation with her, and fought our corner fairly well, not that we could have answered everything to this educated and clever lady's satisfaction no doubt!
The JW's of today are in the main pathetic, they can only quote the bullshit they have been fed, are very ignorant and uneducated, and retreat in any way they can, "Our Web Site.... " That doesn't work, so, " Sorry I have to go..."
Anyway, a seed is always planted when something like this is done, a Seed of Doubt and Cognitive Dissonance, who knows when it will grow, sprout and flourish ?
