What in the hell did I just read? Trigger warning for basically everything. 
I don't even know where to begin, the book seems to be disorganized and is at times hard to read. However not all of her ideas and observations are total whack. Men are often times violent, and much more often so than women. 
On the other hand, claiming

that women are inherently men and men inherently women because men have pussy envy...

it reads very Freudian.
Also, it sounds like Valerie spent time with too many trans women and got a very warped view of them. But then again, this book was written in the 60s.
It's overall.... an interesting book, gives some insight into feminism, transphobia and the struggles of the LGBTQ community in the 60s. 
Read at your own risk.

This manifesto is balls to the wall insane, speeding ahead at 500 miles an hour and chock full of sentences that give you psychological whiplash. THIS book is rage made manifest.
