Today she pulled me aside and said that she disagreed with what I had to say. I asked why and she said that she believed what defectors had wrote in their biographies (she didn't name any specific books). I didn't actually get to counter that (or respond to anything really) beyond the documentary (Loyal Citizens of Pyongyang) I linked in my email which she didn't watch apparently. She was respectful I guess. Should I respond with a critique of Escape from Camp 14 and In Order to Live or should I just brush it off?
I would let it slide for now. Chances are she'll say some other bullshit later that you'll want to confront her on and I think it'll be easier to do so if you don't pressure her too hard right now. If you consistently offer commentary then hopefully she'll appreciate your interest and engagement in the subject and be more willing to listen, but if you force her hand now it could close doors later on.
