That's what I was trying to saw when the Laci Green's video equating this to sexism was posted.

But I seemed to be executed my wording very poorly this time (More than usual, my wording has never been the best :/). 
The whole hating vagina's were meant to be more direct quotes of him, where he's outright said both in his video and his journal that women do not deserve sex or enjoyment cause they wouldn't give him anymore. Even when not claiming sexism and treating it as the mental illness it is, that part is still relevant cause it played a big role in his thinking, his reasoning, his views etc.

Put simply I agree, this is not a case of sexism, discrimination against women or anything. It is a case of a man who is very clearly mentally insane and an example of how the mind can snap and how the human mind can become so disturbed and deranged.
