You sure about that? I know quite a few people who are seemingly only interested in science fiction and gaming it its various forms and aggressively disinterested in anything else. Maybe you know some, too: people who use terms like "sports ball" and whatever the current incarnation of "mundane" (as a noun) or "muggle" is. Believe me, it's no more appealing than hanging with a group of, say, serious football fans (for the appropriate value of "football").
I don't feel the need to demonize anyone, but decent people doing what they feel are innocent things can successfully masquerade as a conspiracy for as long as you care to watch.
