Well, here are the possiblities.
- Jerrab declares to be a man
- Jerrab acknowledges that she's a woman
- says its none of my business, in which case I know she's a woman (a man would never say that)
- refuses to acknowledge the question, in which case I know she's a woman
- deflects with something like "Real Christians would never ask such a question - Christ never did...." in which case, again, I know she's a woman.
So, either way, I will have my answer. Seriously, have you ever met a man who won't acknowledge being a man? That just doesn't happen.
