Welcome to the Monkey House
Slaughterhouse 5 left me with a positive impression of Vonnegut's use of satire, dark humor, and commentary on the absurdity of war and the human condition. However, this short story completely soured any good light I saw him in. The idea that the hero (not protagonist, hero) is a man who sexually liberates women by raping them is extremely questionable, and executed incredibly poorly. I don't shy away from topics that might make me personally uncomfortable to read and think about, but here, it's not obvious what stance Vonnegut is even taking. Any satirical commentary or tension comes from reading about the suffocating, dystopian society that frames the story—not the way that women are "freed" from it.
Not graphic, but definitely don't recommend. I understand that one should take into account the time period in which things have been written, but this is not just a side character marred with racist or sexist stereotypes. The story itself is abhorrent, and I'm left disappointed in a man known to be progressive for his time.
