Fandom and detractors

Over the years, I've come to an odd conclusion. I've listened to, watched and become familiar with a certain species of person who, when faced with sci-fi, furry, anime or other fans, consistently puts them down. Common comments by them about fans are "fatties living in their parents' basement", "have no lives" and so on. You've probably met them if you've gone to any convention, or ran across the SomethingAwful crew.

My conclusion? The types who put down fans seem to fall closer to the stereotypes they're disparaging than the fans they're trying to put down.
