I myself would never consent to receiving ob/gyn care from a nun, because I wouldn't trust that someone whose primary vocation is religious would meet needs like contraception, abortion, family planning, etc.

Would single mothers and queer folk and non-christians be safe in this context? That's a conversation worth having - and one where Nonnatus could rise to the occasion!

But simply telling them not to wear habits doesn't help any of this.

I wouldn't feel safe receiving ob/gyn care from a nun, and forcing her to expose more of her body than she's comfortable with wouldn't fix the problem - it would make me feel additionally unsafe with the medical system!
