In steadfast pursuit of gender equality and to promote nonconformity, it’s become popular in some social circles to start early, very early, by raising young children in a gender-neutral way ...

Most girls will gravitate toward socially interesting toys, like dolls, that help social and verbal abilities develop. Most boys will gravitate toward toys that are mechanically interesting, like cars and trucks, fostering visuo-spatial skills. An immense body of neuroimaging research has shown brain differences between the sexes.
