Authors you can't stand at all?

I agree with Chuck Palahniuk.

Don Delillo is someone I could never really get into. Libra was okay, but White Noise, Mao II, and Underworld were balls.

Orson Scott Card. Homophobic religious nut case.

James Patterson. When your longest chapters are a page and a half...

I don't give a crap about his prose style. His story telling reflects his ugly, irrational views.

Hemingway. I'm obliged to prove my masculinity by killing as many large animals as possible.

Thoreau. I prove my superiority to townspeople by going off and living alone in the woods (by a pond), conveniently overlooking the fact that my very survival depends in part on trading with the same townspeople I have branded my inferiors.  Snobbery.  (In fairness, Thoreau was an abolitionist; so he gets a pass.)

I do, too. So I do value Orson Scott Card.

Salman Rushdie. I've tried quite a few, and at best I've found him vaguely boring. Midnight's Children is massively critically acclaimed, but I found it like One Hundred Years of Solitude transferred to India by a much less interesting voice. Fury was just an embarrassment.

Thomas Pynchon. Gravity's Rainbow was readable for about 200 pages in the middle. It isn't the freewheeling sentences or complexity of text that annoys me, generally, just the impression I get that he's got literally the worst sense of humour in the entire world. He think's he's one zany, wacky bastard, and does remind me an awful lot of Colin Hunt from The Fast Show.

Funny, this was the first writer I thought of when I saw the thread title.  Somebody beat me to it.  However, I can't see anything personal about the author in his writing.  All I know is that Ender's Game was the biggest insult to my intelligence that I have ever bothered to read in its entirety.  I was actually angry when I finished it.  Nothing so juvenile should ever be marketed toward adults.
