Have Barak answer this one:
which passport did you use to travel to pakistan when you were in your 20s?

Or how about:
did you shave your beard while en route or in pakistan?

or how about:
why did you marry an overt racist if you did not share her black separatist philosophy at the time?

or how about:
if you are a Christian how is it that the thing that makes you most proud in your life is the fact your brother decided to turn his back on integrative society, begin dressing like an African, and convert to Islam. What in that makes a self-professed post-racial Christian proud?
