Marston says:

They should accept her however she identifies, and she identifies as a girl. End of story. The kind of shame this school is trying to impose on her, and the way that will control other kids' feeling of freedom to express themselves, is totally unacceptable. It's terrible what they're doing.

The issue of dress reform – to give women more freedom to participate fully in society – was started in the 1850s, with Amelia Bloomer advocating for garments that would allow women to be involved in physical education and sports. It's too bad that the school is enforcing policies from two centuries ago. Women wearing pants was radical in the 1850s; should it be the same in 2014?
