While Mount Holyoke College's recent groundbreaking decision to accept all transgender students — including trans women — was undoubtedly reached for multiple reasons, the insistence of the allies pictured below may have played a part.

Last spring, Mt.

Memorable phrases include: "Support Your Sisters, Not Just Your Cis-Ters!" (which references the word "cisgender," a synonym of "nontransgender"), "Exclusion is Violence," and "Trans Women Belong at Mt. Holyoke."
