I-638 only applies to transgender girls and not transgender boys, and requires all students on K-12 girls sports teams to provide medical documentation that confirms their “biological sex,” according to the initiative’s language. If the initiative passes, it could throw the blue state’s status as a haven for transgender people into question. If the final vote count indicates the initiative has passed, it will also likely face a legal challenge if approved by voters, several legal experts told The Times. It should be challenged and I hope it is. Targeting only girls with this initiative shouldn’t pass muster. I’m deeply disappointed in my fellow Washingtonians.
