A primary way advertisers want to filter is by gender—either because they sell a product that’s specifically geared toward one group (like bras), or because they want to customize their messaging for different audiences. When a company goes into Facebook’s advertising interface to select the types of profiles where it wants its ads to appear, it can select from three options: All, Women, or Men.
Do advertisers want to market people who didn’t fit into one of the binary genders? Is this actually serving Facebook at the expense of both Facebook users *and* advertisers? Can advertisers take an active role here?...
