This is not fair. I don't think anyone suggested those who do NOT give informed consent have a lower desire for a healthy baby. Nor should any blame be pinned on the people happy to give implied consent for encouraging a culture which "belittles the rights of somebody else". If it is valid for you to have your choices respected, it is valid for me to have mine respected. My own implied consent doesn't mean you can't choose not to give implied consent, in fact it doesn't imply anything about you at all. My choices are just that, mine, and don't (and shouldn't) impact on yours.
It is the hcp's responsibility to seek informed consent. it forms part of the principles of medical ethics that they are sworn to follow. It is not a patient's position to decide whether they want to be informed or not before giving consent.

I think I gave consent to my midwives to do what they thought was best throughout the antenatal period when we had many long chats about birth. I began to trust them to do what was necessary, only if it were necessary, and to keep the best interest of myself and my child in mind. So that said, I gave them consent in general to treat me the best they could, and they didn't need to ask for it at the time, because we knew each other well enough.

I had TWO epi's with this most recent birth, both without anesthetic, and both were vital, and they told me they had to do it rather than ask consent.... which was how we had agreed it would be... just do what you have to do and I'll do what I have to do. I don't feel violated at all.

It was my MW's first epi, and she's been delivering babies 7 years.
This sounds like you have given consent (during pregnancy) and during the labour they let you know that they were going ahead with it, and then it occurred. Presumably, you also had a chance to say 'no' if you had changed your mind.

Most people in this situation (given consent, consent confirmed, believe the procedure is neccessary) would not feel violated.
