And it looked like a butcher shop to you? I honestly have no idea what you're getting this from. Do you remember you/your wife giving vaginal birth to her placenta? Didn't that look like a butcher shop?
He might mean butcher shop as in being treated like a piece of meat to be handled as conveniently as possible, rather than consulted or even allowed to guide her own birthing experience. My wife had made similar remarks.
Is there data on this? Specifically I wonder if women who refused it for a first birth still refuse them for subsequent births (or maybe they change their mind?).
