Norway has passed a new law that allows children as young as 6 to self-identify as the opposite sex and change their gender identity on official documents. So far, 10 children have applied to do so and the country hasn't refused a single one. The Norwegian Parliament passed the legislation in June by a vote of 79-13, and "generated little controversy when it was introduced," The Associated Press reported on Tuesday. As long as they have parental consent, children living in Norway can change their gender identity simply by filling out a form online. "Once their applications are approved, they receive a new national identification number that unlocks the ability to update all forms of identification, from passports and driver's licenses to birth certificates and credit cards," the AP reports.
