I guess it's not directly related to feminism, but I came across an old South Park episode called "Mr. Garrison's Fancy New Vagina" and it's a hilarious (but insightful) pisstake on the whole trans issue. Has anyone else watched it?
What I found quite impressive is that the episode was released in 2005 yet it accurately covered numerous angles of trans ideology - with trans racial and trans species absurdities thrown in to prove a point.
Just a warning if you are thinking of watching it - there are some scenes of real life surgery briefly shown at the start of the episode so you might want to bear that in mind if you're squeamish like me. You can cover your eyes and listen to the dialogue for that bit if it helps. :)
