Via Sadly, No!, I give you one Larry Niven, one of the big names in sci-fi/fantasy, as well as a racist scumbag.
Among the group’s approximately 24 members is Larry Niven, the bestselling and award-winning author of such books as “Ringworld”. Niven said a good way to help hospitals stem financial losses is to spread rumors in Spanish within the Latino community that emergency rooms are killing patients in order to harvest their organs for transplants.
“The problem [of hospitals going broke] is hugely exaggerated by illegal aliens who aren’t going to pay for anything anyway,” Niven said.
I read Ringworld so long ago that I don't even remember it, and strangely enough, I'm not feeling an urge to go root out a copy any time soon.
