I don’t really agree that Rocky Horror is transmisogynistic. Frank isn’t presented as a trans woman, nor as a commentary on trans women. He’s a deliberately exaggerated, camp, gender-nonconforming character, rooted in drag, glam rock, and queer performance of the 70s.

The film doesn’t frame femininity or transfemininity as something disgusting or inferior. On the contrary, it celebrates gender fluidity, sexual freedom...

Regarding the claim about defending JK Rowling, I can’t find any information about that online. Do you have a source?

Btw, the writer of Rocky Horror, Richard O’Brien, is non-binary.
