Loads of children read books about dinosaurs, underwater monsters, dragons, witches, aliens, and robots. Essentially, the people who read SF, fantasy and horror haven't grown out of enjoying the strange and weird. - China Miéville
I have no objection to the expression of political opinions in SF if they are an integral part of the story structure. I don't at all appreciate their intrusion for the purpose of converting a story into a political tract, because I consider that intellectually insulting. - Roger Zelazny
[Science fiction is] out in the mainstream now. You can tell by the way mainstream literary authors pillage SF while denying they're writing it! - Terry Pratchett
