Why would any Woman want to be a part of Christianity?

[Nope]

I know a lot of conservative religious people who practice a more authoritarian  type of parenting. If you are brought up in a  family with strict hierarchy where you, as the child, are on the bottom of the family then it is probably easier and more comforting to be part of a similar religion when you grow up. If your parents make all your decisions when you are a child, maybe that creates adults who don't want to make their own choices. So, a woman from such a family might gravitate toward a relationship where her husband had more control over her life.
