Iowa now has its own version of a 'Don't Say Gay' bill, requiring parental consent for nicknames that don't match a kid's 'biological sex'

• Iowa lawmakers are considering a bill to limit gender identity and expression in the classroom.
• The proposed law looks a lot like Florida's "Don't Say Gay" legislation.
• If passed, the legislation is likely to damage student mental health, a psychologist told Insider.

A new bill proposed within the Iowa state legislature would require school officials and faculty members to get permission from parents before calling students a nickname that does not "correspond to the biological sex" listed on their birth certificate.
