Academia has passively embraced stereotypes of mom as head of household and mom as a single parent. Consequently when it all falls down, when a child fails or succeeds, academia blames mom.
According to academia, textbooks, and professors of both sexes, kids who watch too much television are the results of mothers who use television as a babysitter. Successful children are the results of mothers who raised them right.
Pop culture, hip hop culture, and academia must extinguish the idea of solo moms. It's long overdue. The fact of single motherhood in America will not change until Americans fully incorporate fathers, responsibility, and fatherhood in its conceptualizations and discourse on American children and parenting.
Whether a family is married, divorced, separated, thinking about marriage or not, children are never the full responsibility of one parent. Classroom discussion and conversation too often encourage the idea of single motherhood even though this heavy sexist burden promotes the incredibly destructive Supermom/Superwoman myth. A myth that should have died with tragic death of Princess Diana, a woman, wife and mom who held the crown and bore the cross for her (unintentional, and perhaps quite natural) manifestation of the virgin Mary archetype.
The coolest, most well-meaning college professors make mistakes. Often it's a joke meant to break ice or elicit smiles and laughter. But academia cannot continue is NSA like spying and eyeing women's behaviors without casting the same surveying, critical, bitter glances on men who get passes in discourse on parenthood inside academia.
