After the words “transgender” and “queer” were removed from the National Park Service’s website for the Stonewall National Monument, a landmark of the LGBTQ pride movement in New York City, protesters filled nearby Christopher Park Friday with a simple message: “You can’t erase us.

“Stonewall would not be Stonewall without the T,” trans demonstrator Chloe Elentari told Salon. “National Park Service: You can’t spell history without a T,” one sign read. Another demonstrator wrote the word “transgender” on a sign noting the monument.

Trans people were important in a key moment of LGBTQ+ history. The Trump administration banned speaking about this.
