Wicked Stepmothers
Yesterday had some synchronicity. We are currently reading The Boys in the Boat as a family. I posted a quote from it yesterday. It’s a book about the collegiate rowing team that won the Olympics in 1936 but also a book about Joe Rantz, one of the rowers, struggling to achieve the perfect trust necessary for perfect rowing after a hardscrabble adolescence where he was abandoned by his dad at his stepmother’s behest during the Great Depression. She is the classic wicked stepmother, though the author works hard to give you perspective enough to see why she fell into the trap she did. You end up seeing her as more pathetic and meager than villainous.

Not Joe Rantz’s stepmother
Then yesterday I was linked to this mini-essay on wicked stepmothers. The writer first makes a point that the correlation between unrelated men in the home and physical or sexual child abuse is high. About 50x more likely if I recall (though still less likely than not). “Unrelated men in the home” = Mom’s boyfriends or Mom’s new husband. The Wicked Stepdad (or more commonly, the Wicked Stepboyfriend). She then says that similarly the stepmother is much more likely than a biological mother to be emotionally abusive. Its why wicked stepmothers pop up so much in fairy tales. She lays out a series of mechanisms and steps which are point for point what happened in The Boys in the Boat.
Note: the statistics do not mean that any given stepmother or stepfather, or even that stepfathers and stepmothers in general, are likely to be wicked. People have a hard time with statistics emotionally so I think its important to point that out. Most abusers are steps–true. Most steps are abusers–false.
