References to transgender people were removed Thursday from a National Park Service website for the Stonewall National Monument, a park and visitor center in New York that commemorates a 1969 riot that became a pivotal moment for the LGBTQ+ rights movement.

The website deleted all mentions of "transgender" and "queer" in its history of the Stonewall riots, and only referred to the riots' impact on lesbian, gay and bisexual people.

The monument commemorates the historic New York City gay bar where LGBTQ activists — including transgender trailblazers Marsha P. Johnson and Sylvia Rivera — waged an uprising that was a turning point for the modern LGBTQ rights movement.
