Dumbledore’s definitely gay — J.K. Rowling confirmed it ages ago. But is Snape transgender?

Some Harry Potter nerds think so. The Tumblr Snapeloveposts is so dedicated to the theory that it’s hosting its third Trans Snape Week in August, where fans will submit “depictions and interpretations of Severus Snape as seen through a trans-friendly lens.”

“Within the Harry Potter fandom on Tumblr there’s a slowly growing community of people who believe Snape was trans, or choose to explore this possibility,” Tumblr user Ensnapingthesenses, a 26-year-old trans man from Spain, tells Broadly.

“We see ourselves reflected in such a complex, interesting and polarizing figure — which we don’t usually get to do, as transgender fans.”

In building a case for Snape as a trans woman, scholars point to the potion professor’s disdain for “foolish wand-waving,” which author Racheline Maltese describes as “a rejection of masculinity, especially in light of the many moments of phallic humor wands provide us throughout the series.”

Tumblr users also note how Snape has been bullied for having feminine traits.

“I feel like, even closeted, Snape suffered from the prejudices of those around her,” Ensnapingthesenses says. “And I feel that all these incidents make much more sense once you see them in this light.”

Fans further argue that the professor’s complicated relationship with Harry ultimately portrays Snape as the hero’s surrogate mother.

“Harry and Snape’s relationship reminds me more of the interactions between a teenage girl and her mom, where both have anger-management issues because they literally reflect it from each other,’ Ensnapingthesenses tells Broadly.
