Your list IS worthwhile despite what some deletionists would say 

The list (List_of_fictional_characters_on_the_autistic_spectrum) you created is/was up for deletion.  I want you to know there is a place for it: http://wikitistics.com .  No one will be able to nominate it for deletion because it fits one simple rule: it's a statistic, list, or figure.  Some people think these websites should encompass the same scope of a paper book- we don't.  Apologies if this note is directed at the wrong person.  Good luck with your endeavors!
