CBS News, February 13, 2014, The social media giant is adding a customizable option with about 50 different terms people can use to identify their gender as well as three preferred pronoun choices: him, her or them. "Of course Facebook is entitled to manage its wildly popular site as it sees fit, but here is the bottom line: It's impossible to deny the biological reality that humanity is divided into two halves - male and female," said Jeff Johnston, an issues analyst for Focus on the Family, an influential national religious organization based in Denver. "Those petitioning for the change insist that there are an infinite number of genders, but just saying it doesn't make it so. That said, we have a great deal of compassion for those who reject their biological sex and believe they are the opposite sex." "There's going to be a lot of people for whom this is going to mean nothing, but for the few it does impact, it means the world," said Facebook software engineer Brielle Harrison, who worked on the project and is herself undergoing gender transformation, from male to female. On Thursday, while watchdogging the software for any problems, she said she was also changing her Facebook identity from Female to TransWoman.
