Deletion of List of stock characters in science fiction

Comment: Assist in navigation, which is what a Wikipedia list is suppose to do, and there is a book published listing these, which would count as a reference for those obsessed with the suggested notability guidelines, and most importantly, its just , a policy that outweighs everything else on Wikipedia.  These are common stock characters found in science fiction.  Aliens, robots, mad scientists, monsters, whatever.  If you have a problem with a specific entry, discuss it on the talk page.  Perhaps we could list the most popular science fiction works that use each feature, although it would probably be a rather long list
Stance: keep
