Only the even numbers are gender neutral. Think about it...
My simple and smartaleck solution is getting too complex. Let’s do this: pass a federal law that requires all newborns to be given a name traditionally associated with the opposite sex. That would include all names from any ethnic group: K’neisha and Trayvon, Olga and Vladimir, Guadalupe and Luis, etc. Twenty-five years later, require boys to be given boys’ names and girls girls’ names. Twenty-five years later, go back to opposite-sex names. In a couple of generations, you’ll have a good mix of names represented among males and females. People may not like it, but right is right. To make sure there is compliance, a Federal Human Naming-Standards Bureau could be formed and it would have the power, if need be, to assign names.
