On the other hand, boys currently have little incentive to cross the aisle. Those who show an interest in products that are marketed to girls face intense social pressure to take up more masculine pursuits. The developmental psychologist Deborah Tolman has said that boys are more likely to be bullied for playing with dolls than girls are for playing with cars. Bates College sociology professor Emily Kane agrees. In a series of interviews with non-gender-conforming children, Kane found that most parents “felt accountable to an ideal of masculinity that was defined by limited emotionality, activity rather than passivity and rejection of material markers of femininity.” In other words, they feared that boys who did not express disdain towards girly things would wind up failing in their expression of straight masculinity when they grew up. And neuroscientist Cordelia Fine warns that gendered marketing is encouraging boys to shun activities such as “reading or art or nurturing,” which have come to be labeled as girly and thus become “stigmatized for boys.” This stigmatization can have tragic consequences, as in the case of 11-year-old Michael Morones, who attempted suicide after being relentlessly bullied for wearing a “My Little Pony” backpack to school, or 12-year-old Ronin Shimizu, who killed himself after bullies taunted him for being the only boy on the school cheerleading team.
