American Black trans women, in the US, where it was celebrated almost exclusively for a decade. Because society here in the US has to at least pretend to care about trans problems, unlike, say, Russia, or China.
Transgender Day of Remembrance was founded in 1999 by a small group, including Gwendolyn Ann Smith,[4] Nancy Nangeroni, and Jahaira DeAlto,[5] to memorialize the murders of Black transgender women Rita Hester in Allston, Massachusetts,[6] and Chanelle Pickett in Watertown, Massachusetts.[7][8] After Hester's death in 1998, Smith was surprised to realize that none of her friends remembered Pickett or her murder three years prior, saying "It really surprised me that it had already, in a short period of time, been forgotten, and here we were with another murder at the same site.”[8][9] The first TDoR took place in November 1999 in Boston and San Francisco, as both Hester and Pickett's deaths occurred in November.
But we all know that truth or the health of trans folk comes second to "US GREAT SATAN" in your worldview.
