In 1963, Hamilton was arrested for picketing and brought before the court for sentencing. Once again, officials refused to call her Miss Hamilton. She refused to answer. The judge — muttering lewd comments about what he'd like to do to her if she were in his kitchen — ordered her to answer the prosecutor and apologize. But Hamilton was buoyed by rage at the judge's dismissiveness, and by the support of the lawyer assisting her. She refused. She was fined and sentenced to a few days in jail for contempt of court.

The teachers’ objection was not just philosophical; it was philological. The rule, they said in the French version of Slate, was a parvenu (it was enunciated in the 17th century and became widely taught only in the 19th century) and politically motivated (it buttressed French laws that denied women equal rights). Besides that, they said, the rule encourages children “to accept the domination of one sex over the other” to the detriment of women.

“We are committed to making sure that our show highlights strong women in a way that appeals to girls and boys in equal measure. If we hope to achieve gender equality in our lifetime, we can’t only educate one half of the population,” she said.

Millennial men share the same values as women when it comes to work-life balance, equal rights, pay transparency and meaningful careers. Millennial men participated in the Women’s March, rallied around Equal Pay Day and have been involved in many protests about equal rights. Instead of focusing on gender, we care more about equal rights for all and protecting and supporting our local communities.

“Data shows that gender is on its way to becoming much more of a nonissue, just another human variable such as height, hair color and shoe size,” says Laura Maness, CEO of Havas New York. “This is not to say we foresee a time when gender will be entirely ignored; simply that it will be increasingly less of a focus and factor in decision-making.”

The panic greeting requests for teachers to tackle homophobic, transphobic and sexist bullying, while encouraging children to creatively express themselves is, quite frankly, mind-boggling. All the evidence shows that rigid gender stereotypes cause real pain and difficulty to children (and adults).

Boroditsky's research has found that the way people often describe objects correlates with the object's given gender in a language. In German, for instance, "bridge" carries a feminine pronoun, and Boroditsky said Germans are more likely to refer to bridges as "beautiful" or "elegant," both typically feminine traits. Spanish-speakers, meanwhile, will refer to bridges as "strong" or "sturdy," as the Spanish word is masculine.

While the hashtag does include disabled people, many of the most popular tweets, Facebook posts, and other social media shares feature familiar faces: white, nondisabled cis women. The slew of ensuing mainstream media coverage has reflected this in turn, largely ignoring the issue of disability in conjunction with sexual harassment and violence.

"We need a shared vocabulary for having a this difficult conversation: not just a set of words to describe our experiences, but a set of concepts that help us understand how our words will affect the people reading them."

But it’s possible that many of the differences between young boys and girls come from the way we approach child rearing, and the messages kids get about how boys and girls should look and behave: the cultural stereotypes we impose on them that become self-fulfilling prophesies of sorts. “It’s almost entirely cultural,” Brown says. Natal sex, in other words, is less predictive of who your children will be than of how you will treat them.
