Men in Ewes' Clothing: The Stealth Politics of the Transgender Movement
An downloadable PDF archived from "A Women's Journal". It talks about how identity politics are in and of itself a political statement, how analyzing said politics is NOT intolerance, and how the act of showing off a penis at a women's safe space at a festival proves the politics being expressed by feminism are not understood at all.
It also debunks things attributed to radical feminist thought, which are actually smears.
Not so much an attack on Transgenderism, as it is an attack on Libertarianism and the concept of inclusion for inclusions sake (As the writer says, if they wanted to be inclusive they'd have invited any man walking down the street. Inclusion isn't the point.)
Worth reading imo.
