While we’ve spent a fair amount of time examining the negative effect of princesses and Barbies on the development of girls’ perception of themselves, we haven’t paused to question the consequences of the video games marketed to boys that have names like “Manhunt,” “Thrill Kill” and “Mortal Kombat.” We don’t blink twice when the NRA releases a free target-shooting video game (one month after the Newtown massacre, no less) and marks it as suitable for boys ages 4 and up. We indoctrinate boys and it starts early.
