Have you ever read a short story or novel by an author and been turned off so much that you never read or wanted to read anything else that this author had written? For me, it's Joe Haldeman. I read his short story "More Than the Sum of His Parts" and was revolted by one part of the story. A part where a man whose body has been repaired with mechanical limbs has torn a woman in half to see how strong his new body is.
I felt, and still feel, that there were better ways of doing this than splitting a woman in half during sex. I wondered if this section was added just to show that women were disposable. Even after a year this story still sticks me. The man can write, but I'm also afraid that I will find more of this disrespect for women in his work.
Thinking back on the story I realize that he's showing how the repairs are turning the man's mind, but the lack of remorse for what he's done...that just didn't set well with me.
