She makes a poor argument.
This has been explained to her repeatidly but she only responds with "but it's not in red writing!!!".
You know what else isn't in red writing (or any writing in the bible that people can find) is the assertion she's making that jesus wouldn't have considered an unborn a child because of jewish tradition.
Just saying, she's making a logically flawed argument so you will not win by attempting to use logic.
