Most women (and men) believe the things their parents teach them.
The thing with conservatives is they want to 1) prevent any other information flowing to these women, religious indoctrination only 2) get these women pregnant young so that they don’t have a chance to gain independence
So yeah in those cases you have grown women who believe these things. The Duggars are an example of the ‘quiver full’ movement in action. Letting their son abuse their daughters young so that they get used to it and defend it as normal.
