I think lying to medical practitioners refers to not telling them you smoke or downplaying how much alcohol you drink rather than withholding your moral views from them.
It’s also her job to reassure you that your medical team can make a potential next pregnancy safer for you. My community midwife went out of her way to reassure me I could have my birth wishes next time despite how my first labour turned out. I told her we weren’t having any more, she jokingly said something about it being criminal to not have any more after making such a cute baby and that was that.
I understand that your traumatic pregnancy and birth experience will perhaps have coloured your response so I appreciate her comments will have been particularly difficult for you.
