Cass Clemmer is a Washington, D.C.-based trans, queer artist who uses "they/them" pronouns. Because they were born with female reproductive parts and have not completed a full medical transition, they still menstruate. If that disturbs you, well, grow up, weirdo.
Earlier this month, Clemmer posted a photo of themself on Instagram and Facebook, which shows them free bleeding while holding up a sign that reads "periods are not just for women #BleedingWhileTrans."
The powerful photo, and an accompanying poem in the caption, have gone viral.
