I hope it goes without saying that I don't want anybody to be mistreated or even to feel like they're not getting proper and supportive care, but I really wonder about some of these self-reported incidents.
Some really dumb people might describe a doctor saying something like "I told you this before. You say you want a healthy baby, but you need to quit the recreational drug use and drinking while you're pregnant" as verbal abuse.
You can come up with a million scenarios like this during the course of a pregnancy where an idiot might interpret a doctor's genuinely compassionate efforts to help them as "abuse".
