http://www.slate.com/articles/double_x/doublex/2012/04/hen_sweden_s_new_gender_neutral_pronoun_causes_controversy_.htmlHen was first mentioned by Swedish linguists in the mid-1960s, and then in 1994 the late linguist Hans Karlgren suggested adding hen as a new personal pronoun, mostly for practical reasons. Karlgren was trying to avoid the awkward he/she that gums up writing, and invent a single word "that enables us to speak of a person without specifying their gender. He argued that it could improve the Swedish language and make it more nuanced.
Today's hen champions, however, have a distinctly political agenda. For instance, Lundqvist's book is published by a house named Olika, which means "different or diverse." Olika only publishes books that "challenge stereotypes and obsolete norms and traditions in the world of literature." Its titles include 100 möjligheter Istället för 2! ("100 possibilities instead of 2!"), a book for adults who "want to give children more opportunities in gender-stereotyped everyday life"; and Det var en gång ... en ritbok! ("Once upon a time there was ... a drawing book!"), the first "gender-scrutinizing" drawing book for children that "challenges traditional and diminishing conceptions of girls and boys, men and women."
