It's worth noting that the Women's Flat Track Derby Association (WFTDA) has an incredibly progressive gender policy. It is really cutting edge in the global sporting community.
Here are the main points:
"The Women's Flat Track Derby Association (WFTDA) is committed to inclusive and anti-discrimination practices in relation to all transgender women, intersex women, and gender expansive participants, and aims to ensure that all skaters', volunteers', and employees' rights are respected and protected.
The WFTDA recognizes that identifying as transgender, intersex, and/or gender expansive is not in any way related to an individual's eligibility for participating as a volunteer or employee. An individual who identifies as a trans woman, intersex woman, and/or gender expansive may skate with a WFTDA charter team if women's flat track roller derby is the version and composition of roller derby with which they most closely identify.
The WFTDA will actively work to promote a climate that is welcoming and inclusive of transgender, intersex, and gender expansive participants. Any conduct which fosters a hostile environment for any participant on the basis of gender identity will not be tolerated. In addition, the WFTDA will continue to increase its knowledge of trans, intersex, and gender expansive issues through ongoing education for volunteers and staff. The gender identity of any and all WFTDA participants is considered confidential and private."
